Thanks for the replies so far.
So far in my search for material to make my own seals, I have walked the aisles at Lowes and Home Depot, the hardware store, 2 hobby shops.......and searched the websites of all the auto parts store, Grainger, and a few others.
I have not seen anything in person that looked right.....I've not seen anything online, that by it's description, I could be sure it was what I wanted.....for a reasonable price anyhow.
I will be going to the the annual Turkey Rod Run car show and swap meet in Daytona this coming weekend. There will Camaro vendors there who might have repros that I could look at before buying. If that doesn't work, maybe someone will have suitable material to make them from.
If that tuns up nothing, I will check into the 1/32 thick neoprene.
On the suggestion of the Frost King tape, I am not sure how 3/8 inch wide tape would replace an oval shaped piece of flat rubber that is about 5 by 8 inches wide.
Thanks....Dave
