Just purchased a 1957 Chev with a 235 and 3 speed on the column. There is an excessive oil leak at the rear of the pan so presuming it is the rear main seal. Want to order a new seal and gasket before I take it apart. Was on the Fel-Pro site and they offer a 2 pce rubber seal, part # BS13363 and is available locally. Has anybody ever tried this seal compared to the original rope style? Looks much easier to install and hopefully seals it up. Any comments?
