Hi guys, I did a search and saw several posts discussing rear main seals but I still have some questions. I have a 49 P18 and have it apart to replace the rear main seal. I purchased a rope seal kit as spec. for a 49 218 L6. After removing my rear cap I see I have a neoprene seal. According to my Plymouth Service Manual 1946 to 1953, the neoprene seal is for the 1953 model. Rockauto.com still lists a rope seal for a 53 and a picture they show for a neoprene 55 Canadian does not look like my seal. Another point of confusion - I saw posted in a previous post that a top half of a neoprene can't be replaced with the crank in place. My service manual states that the upper half "is easily removed. My questions are - are the rope and neoprene interchangable? should I order a neoprene for a 1953 or should I try to use the rope seal I purchased (maybe the guy before put in the wrong seal?), and as the manual states can the top be replaced with the crank in place? Also, I noticed that on the crank the edge of the rear main bearing thrust face is sharp / has burrs - so I will dress this. Any help would be appreciated - thanks!
