Cowl induction seal

[Lynn]

Digging up an old thread here. On the 69 Z that I am working on, I pulled the flange off to install a new seal. The flange has a GM sticker on it, but it isn't exactly like the original on my car. Mine is not perfectly round, a a small part on the passenger side is slightly egg shaped. BUT mine still has the little 90 degree lip all the way around. This one just has that part cut off, so there is no lip to hold the seal.

Hope that makes sense. can post pics tomorrow.

So, two questions.
1. Are all the over the counter NOS flanges like that?
2. How to you get the new seal to mount correctly? Glue?


Thanks for any help.
