Just curious: I have a 228-302 rear main seal made by a company named Fitzgerald Gaskets. It is in an unopened envelope with their part number and "To replace part No. 2091026" which is GMC's number. The address on the envelope does not have a zip code, which should place it pre-1964. Good chance it has asbestos. I'm keeping it for my 302 if it ever gets finished.
Would you use it?
