I have a question? Instead of working on the bottom end of the strap, why not drill out the pop rivet and shorten the strap from the top? Looks like it would be very easy aging quick. I have been thinking about this window thing for a while and was going to approach it from this prospective. VJda

I understand you thoughts, but sometimes it just doesn't seem like a good idea taking a drill to things if not absolutely needed.. But if you decide to give it a try definitely let us know how it works....who knows, maybe you'll find a better way. Good luck.

Another part of my thought process is the fact by doing the rivet thing you world be shortening the strap part and not the elastic part. I can't figure which would be more appropriate. The pop rivet is right in front, very easy to access. Jda

Been there, done that. Worked ok for a couple months, but the elastic band just stretched more. Tried to tighten it a second time, and the elastic is pretty much shot. My guess is folks who try this will end up with the same results. It's a short term fix, at best.

I'm now investigating ways to replace the elastic band with a small bungy cord.

It's just a poor design if you ask me.

yeah I was thinking that the "fix" would probably only work until the elastic stretched again. maybe a higher quality elastic would work for a more extended time. I figure G.M. only used the cheapest piece they could spec.
thanks so much to the original poster. I think I'll give it a try to see how long it does perform as it should. other than storing your car with the top down all the time, I don't hold out much hope.

Yea.....I agree that any fix involving the org. strap will probably be just temporary. I'm sure there is probably some type of elastic piece that would be much more durable. Not sure a bungee chord will work as it is quite a bit thicker than the org. piece. May not be enough room for that extra thickness when things are all folded up. Probably worth a try though so hope whoever posted the thought keeps us in the loop as they try it.

Two points I'll make here.

First, apparently there are 2 different straps out there, and I have no idea when they made the swap. One is 100% elastic (most of the later years have this one) and it apparently replaced an earlier version that looks like its either leather or some other material with an elastic strap attached to it. As my video shows, I have the all elastic strap, so messing with the rivet end is irrelevant.

Second, my whole basis of this repair was to try and keep from having to do anything permanent. Furthermore, the angle that you would have to drill out the pop rivet wouldn't be the easiest to get to, but it certainly is far from impossible. The average person usually doesn't have pop rivets in their inventory or even a riveter to work with.

Lastly and most importantly, they don't sell replacement straps, so it won't be a quick swap out. Sourcing a proper replacement will be...time intensive.

I don't feel that I've been foolishly optimistic with this and realize that it might be a band aid over a machete sized wound. However, it's such a simple repair and VERY worst case, you'll end up right back where you started...no better, no worse. If it doesn't work out for you, you can still join the "2 finger pull" club that most were already in anyway. Also, which type of strap did you have? Perhaps one type is more prone to stretching than others (see my post above).

Since it has been brought up, I will update everyone with my status. About a month in, I felt that the 1/2" move wasn't giving me the clearance I felt comfortable with so I went back to 3/4". With nearly 3 months in, currently at 3/4", I'm near an inch of clearance. It's close to what it essentially was, if not only marginally less. I never park my car with the top down, even when in the garage.

I will keep everyone updated as time goes on.

I'll reiterate what I saw on that thread. It does offer another possible fix, but it'll only work for the early strap designs with the leather portion.

"The pictures also illustrate that you have a different elastic strap design than the later models. The later models don't have that leather/vinyl portion and the top strap and it attaches in a different place. This only furthers to complicate streamlining any one type of repair. A repair on one strap type may not necessarily work on the other. (ie - There is nothing to sew a new strap to on the later models and would require drilling a rivet out that's in a much more challenging place to reach)."

If you have an early model strap and simply stretching the strap doesn't work, his proposed method could be worth a shot.

As the warm wea ther continues to roll out, i'd like to hear if people are getting their tops fixed!
Would you happen to know the TSB number?
Thank you

I just found it #09-08-67-013C

Sorry...beat me to it.

The TSB images look like they were a 2009+ design fix. If you have a 2005-2008 that uses the old straps, it looks like ordering a new pair for $25 and swapping them out is rather easy.

Those of us with the 2009+ strap design aren't able to easily swap ours out...at least not without removing the top canvas completely.


For now, this repair will suffice for me. Coming up on 4 months, I'm still not having any issues.

My top is just touching the rear window area slightly. ( passenger side rear)
I stopped at the dealer to ask about the TSB. He said there were 4 items on the TSB that would have to be checked. I'm sure the other items are good. I saw they said to move the screw as a fix if that is the problem. That TSB showing the screw may be for the later carsThe question is buying new straps ( low cost ) I thought about this and the new strap can stretch and have the same problem. The dealer said it could be any of the 4 items listed . It may not be the strap. He said his shop can check it out but I probably will also purchase the new straps .. I have an 07 and the top works perfect except it's slightly touching the rear near the window. Thanks for the info

I've been working on the problem for months, finally ordered the replacement straps for the fix. I have an early model with the two part straps. The kit arrived with the two straps, two bolts, and two pop rivet, plus four small metal clips. Any ideas where the clips go? Our what they do? Couldn't find anything like them on the car. Any ideas? Jda

I have a 2006 and have been told the straps are different and are available from Chevrolet. Does anyone have the part number for the straps

You have to give the dealer your Vin number for the correct strap. This owner has a 2008 car and I take the same stap on my 07.

The GM P/N is 89024073 for the strap on vehicles built prior to 3/15/2008. If built after, the P/N is 19207656

On some websites it will be called a tension arm or tension strap. On other websites it will be just a strap.

Of note, it seems significantly easier to replace these straps on the pre-2008 version, as the rivet is right in front of your face and fully exposed. See the above video posted by enventr if you want to see the location.

In all honesty, I don't think it's possible to get to the riveted portion of the post-2008 version without removing the canvas of the top first. The riveted on portion of the newer design (as you can see on my original video I posted) is tucked way back and isn't mounted transversely as it was in the original design. This makes it impossible to drill out and get to without the full removal of the canvas top.

Given this information, I'd suggest that the pre-2008 designs just replace the straps instead of making the repair listed here since it's not going to be a whole lot more work and is easy to access. However, those of us with the post-2008 design, it's going to be a better bet to make the repair listed here. Replacing the straps on the post-2008 design will almost definitely require dealer/specialist intervention.
