I hope I don't step on any toes here, but I do not recommend the OER trunk weatherstripping. It may be a durable and well made product, but it is entirely too stiff and too large to work properly on the trunk.
After spending hours just trying to test fit the OER stuff into the trunk channel(this is on a completely clean and newly painted channel) I came to the conclusion there was no way it was going to fit. Along with that I tried closing the trunk on top of it with it only partially in, and the trunk would not close unless I raised the latch way up out of alignment. Slamming the trunk against it was like hitting solid rubber.
I will say it looks like quality material, is very dense and probably would hold up well in the right application. But a firebird trunk doesn't appear to be that application.
So in order to get something that works, after a lot of research I went with Metro Moulded Parts. This stuff is made in the USA and appears to be a quality product. It's not only smaller physically, but also less dense than the OER stuff. Additionally, it is hollowed out to allow it to compress into the trunk channel.
Here are a good picture showing the differences. Metro Moulded is on top and has the holes in it. You can see how much bigger the OER stuff is, especially the base area that goes into the channel.
