My rear main seal is leaking a bunch on my 70 MK III w/stock 460 and trans. I'll be pulling the tranny soon to replace the flexplate so I was thinking I'd whip out the rear main seal while I was at it. Some questions... 1. Am I making things worse or better by wanting to do the rear main seal at the same time as the flexplate? 2. Fel pro makes two kits, both are two piece, one is rubber the other is "vitron" - which is better? 3. Do I have to drop the oil pan? 4. If I have to drop the oil pan, is there anything I should do with the oil pickup assembly? (seems to be oiling fine) 5. If needed, will dropping the oil pan be harder with the tranny removed? 6. I know I'll need two new exhaust donuts and a oil pan gasket, anything else you can think of?
