I have a few early V8's (265 and 283). Whe I search for a replacement rear main seal, I am a little confused. I see some of the classic part dealers mention the replacement for the rope seal mad out of neoprene ($27 to $35). Then I see on my gasket set that it is good for years 1955 to 1967 with only one seal in it. Is there a specific seal to use when switching from rope to neoprene? Or is this just an opportunity to sell the same common seal with a high price?
