Ok now I'm trying to reassemble the trim after replacing the rusty header. Naturally nothing seems to fit, but all my projects are that way.
On this stainless t bar, on the under side there was some type of sealer on the edges, looked like a foam. What do you use in that area? Windshield sealer?
On this trim piece there's 3 pins that are supposed to snap in to hold it in. My t bar only has one installed from the factory. The other 2 were never installed. I guess mine was a Friday car. Any ideas what I can use to attach the other 2. Some type of aplastic retainer I can put in the holes ?? ( That white stuff is a repair I did, the underside had a crack in the fiberboard from it sagging )
I use CR Laurence's CRL 7708 as my go to sealer when wanting to make sure I seal up areas to prevent water leaks in most areas. I do not worry about the foam that GM used and clean it off due they never figured these cars would last over 40 years...so when install this trim I pump in the CRL 7708 really good to make sure it never leaks but it still can come back out if needed due to the CRL 7708 does not harden and stays gooey all the time.
AS for your studs for your trim. This must be like a 1970 or so due to these studs were installed BEFORE they wrapped it in the vinyl and trying to get something to make sure it will stay put on the fiberboard backed part is kind of a hit or miss situation. For me doing this type of work for living know I would not nor could not waste any time on it and just buy a new one due to if it failed and it released. I would have to deal with it time an time again and it is just not worth my time. I have several ideas... but once again...by the time I did what I needed to do...the cost would be close to buying new one. So best of luck with that.
Thank you D U B for responding. Ill try to get the CRL 7708 sealant. As for the studs, the metal retainers that are supposed to be riveted in the t bar were never installed. The only way to put them in is to separate the 2 halves. I'm not going through that. I found some plastic retainers at napa that are used for attaching bumper covers on new cars that might work.
I guess quality control was absent the day my car was on the line.
Thanks again for responding

Does this CRL 7708 stuff behave like mozzarella cheese....sticks to everything and stretches out forever if it gets on something you do not want it to? I have tried 3M black super weatherstrip adhesive in the past and found you have to be fanatically careful when using it or it gets all over everything.
I've never used CR Laurence's CRL 7708.... do you just pump it in around the edges or completely fill the cavity?
I pump it in the forward area and build it up so I know when I put the trim in place I push it down and let it flow and seal well. I also make a conscience effort to make sure I apply it to the underside of your trim at the front edge of the windshield frame area so I know it is sealed. I also apply it on top of the two stands where the two screws go that also hold the trim in place so they are sealed.

YES...the CRL7708 sticks well and if oyu get it on you it can get stringy and be quite messy. I generally do not give a hoot due to I usually will mask off the area so the clean up is easier and use the 3M 8984 to get it to come off stuff.
The weatherstrip adhesive is nothing like the 7708 and it is not a big deal. (in my opinion) if you are watching what you are doing and take precautions.
NOW there is also another product which I would not use for this particular discussion and it is the CRL 1716 and it is a pump grade product that flows and SKINS over and I use it in many key areas also for keeping water out. Its proprieties does things that the 7708 cannot do.
