I'm putting my 66 skylark back together and wanted to make a few gaskets. Primarily for my rear quarter extensions , but also for my tear drop. I saw advanced auto sells a blank paper sheet, I was hoping for something in a rubber or poly material. Almost thinking of using rubber roofing material or similar. Thanks for any advise.
I bought a roll of neoprene... used it for the qtr extensions and for the heater box and front vent seals. Seems near identical to the original material. https://www.amazon.com/gp/product/B08XPKYJ2B/
