Default T-Top Problem

Hello all,

A couple of weeks ago, I listed a post about one of my T-Tops on my 77 vette not laying flat when in place on the top of the car as compared to the other side. I was referred to another post called "T-Top Warp" that described what sounds like the same problem I have on my car. The only suggested fix I was able to find was to pad the warped top and load some weight on top of it for a period of time to hopefully straighten it out. I am a little concerned about trying to do this as I am afraid it will cause some damage to the finish of my top. Has anyone else had this problem, and if so do you have any other suggested solutions to resolve the issue? What about a new T-Top? What would the cost be and where is the best place to purchase one? Please advise and thanks in advance for your help.

Have you tried adding or removing shims.You can buy shim kits from Ecklers for not very much

I'd look on ebay for t-tops, or some of the vette salvage yards.

Is the top wavy or just high in one spot. My 75 passenger side sat high and turned out that the top was starting to separate from the frame. If this is the problem I was told that you can rebound the loose section.

It is warped both where it touches the windsheild so that it is very apparent when you are standing in front of the car looking at it, and also when you are behind the car looking at it from the rear. It is just as if it is bowed upward.

thx

It is not wavy, but just high in the center of the T-Top. You can see it from the front and also from the rear. Any additional info regarding how to rebind the top to the frame? Is it easy to tell if this is the problem? I have not taken the inside cover off the T-Top to inspect it closely, but it sounds like this could very well be the problem.

This is the warp being discussed.

I suggested the weights on the top.

After another several weeks with a 15lb weight on the front, the warp is less than before. However, I think it needs more time, weight or both. I don't have the headliners on my tops and recently replaced the weatherstripping, so I'm certain that my tops are not separating.

Another problem with these cars are the trim pieces. I can see the trim piece in the picture is like mine....far from straight, dipping just about where the top is going up and making the T-top look even more out of whack then it probably is. I am not saying you don't have some sort of warp but with a slight warp and the trim being less than straight, things can start to look really screwy really quick. This looks almost identical to my '80.

My gut tells me once fiberglass has warped it's going to stay that way. You might want to try putting weight on it as described near a good heat source like your furnace so it warms up, but not hot. Put a blanket or something to protect the T-Top surface. Let it sit a week or two. If still warped then I'd just replace it.
Good luck.

Yes, mine looks just exactly like yours in the picture. You can see it raised in the front and also in the back. What causes this anyway?

Do you have any issues with wind noise or water leaks due to the warp? I have not had mine out in the rain since I purchased it back in January so I am not sure if mine leaks or not. I hope note..............thanks

If it were only cosmetic, I really wouldn't waste much time worrying about it. But, the bow keeps the weatherstripping from sealing across the front. I did just replace it before winter, but even after months of the top being on the car, the WS doesn't seem to be smashing down allowing all the gap to close.

It is a really agravating problem. I may shop around for another T-Top if I can find one at a decent price. But then more than likely it will have to be painted to match. Sounds like there is no cheap fix for this problem. I wonder what makes these things warp?

The glass one on my '80 sat the same way. I think it is a combonation of the trim at the windshield and slightly the top itself. I learned to live with it. Peace,,, Moosie

Did you try what I suggested earlier re; weight & heat? I'd give it a shot. Since it's cold out and we're not driving our vettes much this would be the time to try it.

Mine did not look like that it was from the corner in. I was able to determine it was separating by removing the drivers side and pushing down on the top. I could see the fiberglass moving and the frame staying stationary. To rebound is a matter of working some sandpaper in between and sanding both surfaces. You can then use Vette Bond, available at paint supply shops, in between the two pieces and then use moderate clamping pressure.
