Does anyone know the correct dimensions of the o-rings? They are the ones that go between the oil filter adapter and the 1/4" spacer and also between the spacer and the pump body. Just eyeballing, the larger one looks to be approximately 2-5/8" diameter and maybe 3/32" thick. The smaller looks about 3/4" diameter and 3/32" thick. I am not talking about the pump body to block o-ring. Possible sources? 74 Challenger, bought it new. In 1978 I replaced the original 318 with a 446 and 727. Mild cam, Jardine headers, and Holley Sniper EFI. New engine! 511" RB, Edelbrock Performer RPM heads, Eagle rotating assy, Comp hyd roller cam, Doug's 2" headers.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
