Trunk Lid Install and alignment -Mach 1
#1
Team,

I'm feeling like and idiot. I installed the trunk weatherstrip and tried to install the actual deck lid. The weatherstrip is very stiff and I cannot get the trunk lid to latch.

Anyone else tried new weatherstrip for the trunk and have closure problems? The car is still disassembled enough to make alignment wit the rear window trim or the QP extensions impossible at this time.

The latch receiver is in its highest position. Any suggestions?

Smart enough to put in a headliner, but I cannot install a trunk lid!Dodgy

What are the height levels on the trunk lid and quarter panels? The important part is the alignment height along the front of trunk lid and the rear window panel. can you post pics?

When we changed our weather stripping the trunk lid sat higher when shut but after a while it returned to normal when the weather stripping compressed.

Although I went through a similar experience with my 69 vert, it may have bearing on yours. When I initially completed the restoration a few years ago, I used basic trunk weatherstripping (approx $8). Three years later I still had issues with closing the trunk because the weatherstripping never compressed properly. I removed it and installed weatherstripping made by Daniel Carpenter Reproductions ($14) and within 2 months it made closing the trunk lid nice and easy. It also seals the way it should. The new stuff was noticeably softer and had the correct profile.

I can't get it to close, so I cannot measure the height. Is that what you mean, The elevation of the trunk plane above the 1/4 panel line?

I will try to look at who made this stuff. I bought it several years ago, and it was labeled for 71-73 Mustang, all body styles. It seems to sit tall.

Having a hard time closing the trunk lid after installing new weatherstripping is pretty much the norm for many of us who have done it.

Use some strips of paper cut from a brown paper bag. Lay them around every 6 inches or so over the seals and hold the trunk lid down as far as possible and have someone remove the strips to find the interference points.

If it is just a small area that is keeping you from proper alignment and closure, you may be able to massage the tight areas down with light blows from a rubber hammer on the inside lip of the trunk. Once it is closing, you can get in the trunk with a flashlight and have it closed so you can find any areas that might not be sealing properly.

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

Still no luck with this thing. I put on one of the 1/4 extensions and the alignment is perfect. Gaps are parallel and perfect down both sides of the lid compared to the 1/4 panel.

Should I cut weep holes in the seal? Any other suggestions. I have left a "load" on the seal for the last couple of months, and I still can't get it there.

Thanks for any more helpful suggestions.

I just put the weather stripping on mine and its a tight fit. I have to close the lid a little harder than previously but it now has that solid feel when its closed. I concluded that the new rubber hasn't compressed yet.

When installed correctly, the weatherstrip will compress within a few weeks and the trunk lid will close smoothly.

The first few days are the hardest with the new rubber. Same for the door weatherstrips.
