The pan will be an easy drop, while in you can inspect and fit the shims on the rods to the proper clearance if there is wear, the beauth of babbitt,
The rear main, I have heard that the upper can be left alone and only the lower cap portion be changed and see if this helps, I have a best gasket rear main for you to feel and will bring the same when I venture out to Sandwich. In just a few hours, you could have the job done and see if it solves the problem, the lower is the weak part of the seal and under most hydro pressure.
