[FC] '61 Rampy info

[wern3 at juno.com]

Guys
I am rehabbing my transaxle for my 4 speed Rampy, and have some ID #s cast into the casings:
Tranny:-GM 6 over 3833193 over A244
Diff:- BF2-21 over 3780270
Are these correct for a 1961 Rampside?
I removed the clutch / P.Plate /Flywheel to find a badly burned early model pressure plate and 9" clutch disc which I have since ordered replacements for.
Is the driveshaft any different froma '65 car unit? I may have mixed up the original one with a spare i have in my garage from a rebuild on a '65 model 4 - speed>
Thanks
