Wing window gaskets

Anyone have any thoughts on the difference between these two gasket kits?

The cost is essentially the same.

Any others out there?

Thanks!

Yes, they are both made from the same MFGR and do not fit without some kinda big tweaking. I have heard some windows have been broke trying to close them.

I got a set from Mac's and they were made by Dennis Carpenter. Not fun to install and Yes the windows feel like they are going to break when you close them.
I have not found any others yet but if I do these are coming out!!

Guys, I have talked to Dave at Restoration Specialties a couple times in the last few months about the wing gaskets and he says that he has a source working on making new ones. He said when he gets a set he will contact myself or Tim. Who knows when this may happen R.S. is know to be slow at everything they do.

Thanks for the info guys.

I'm going to look at a parts van today, so hopefully I can get some salvageable gaskets off of that. Otherwise, I think I'll wait on swapping out the ones on mine.

Thanks, I would like to hear how this works out as well.
I'm currently looking too.
