Trunk Weatherstrip Coupe/Convertible 1965-1970 is rated 3.4 out of 5 by 7.
Rated 2 out of 5 by from Too thick I bought this based on reivews. Installed easily and based on comments I've read, I adjusted the lid and let it be for over a week thinking that it might compress. I see no change at all. The fit is just not good and I'm planning to remove in favor of another made from softer material (or OEM if I can locate that).

Rated 1 out of 5 by from TOOOOO THICK Uncompressed, this WS is about 3/4" thick and it just doesn't compress enough. Trunk fit perfectly before installing it and now it's up 1/4" high on the sides. Adjustment can reduce this, but causes a bad fit in other areas. I'm planning on taking it out and installing a hollow "D" section.

Rated 5 out of 5 by from fits well look at the picture closely. This mounts on the trunk not the seam around it. Best bet pull the trunk off, turn upside down and glue. No directions with this but it is simple to remove 4 bolts and get it attached right.Buy the glue as well.

Rated 5 out of 5 by from Excellent fit! I bought this to replace a weatherstrip purchased elsewhere. The other product was much too thick. This fit perfectly and installation was fast and simple. Wish I had done this the first time :-)

Rated 1 out of 5 by from Way too thick It's made out of a foam that is way too dense and it won't compress. Now I have to remove it and find another that is like the original.

Product Questions

is this weatherstrip suppose to sit on the seam when the truck is shut

Asked by: freddy 1
This is supposed to seal against the raised edge of the trunk opening.

I bought trunk weatherstrip for a '64 Mustang coupe. It measures 128", but trunk is ~140" around. Am I to stretch it that much? Seems pretty tight when I do.

Asked by: SteveJ
No you shouldn't have to stretch it, it should be long enough that you have to trim some off the end. please call and talk to one of the customer care reps toll free at 1-800-888-6473 for assistance.

does this weather strip glue on the trunk lid

Asked by: 65stang
Yes, it uses a specific weatherstrip adhesive, which is part number AD3M
Answered by: CJ Pony Parts

I am having trouble with the trunk seal I currently have. It is too thick and the trunk does close correctly. Of the two brands you carry for the 65 coupe, what is the one that would solve this problem? Thank You

Asked by: GPenna
Both are very similar. Scott Drake's are just a bit higher quality versus the generic product.
