In this case, no damage to the crank, never been even polished. Since 1956-62 calls for the Neoprene (rubber) seal, I am having a heck of a time understanding why that seal is so hard to get.
Just today, my machine shop said I would be getting two new Fel-Pro RUBBER seals. UPS arrives, and guess what? TWO of those impossible to cut ROPE seals arrive. I tellya, some 'expert' somewhere talked Felpro into providing JUST the rope type. Now I have my machine shop looking for the PROPER, year original RUBBER seal. I got nothing better to do but wait days and days and days for a rear main seal I can actually USE!! LOL!
The Best Gasket Rubber Seal should arrive tomorrow and then we are all good, but WOW! Are you kidding me? You would put a weepy rope seal in when in 1956 it was realized that they are insufficient and the neoprene rubber one was THE rear main seal recommended by GM? But as Dave says, the rope is still needed for if you polish out the pits. BUT NOT the new style FEL PRO! I defy ANYONE to try and cut this seal. It simply cannot be done and still have the main shell part(kevlar) in tact at the junction. Not gonna happen! I do feel the Best Gasket rope seal would be fine. You have to wonder who the management genius that made the decision to scrap the rubber one was and what IT was thinking! It is THE 56-62 suggested seal! Hello? LOL!
