I have the entire drive train out of my '67 L30/M20 and thought I'd get a few comments on what I should look to repair/replace while I have lots of room to work. Car is getting a new clutch (all associated parts like flywheel, bell housing, linkage, Saginaw, Hurst, etc. rehabbed) I also installed new manifold flange studs. What else? Oil pan gasket? - Do I need go thru jacking the engine up to remove the pan? Rear main is not leaking at all. Thoughts? Thanks.
