Need some tech advice

I am working on a club members 1963 car, he just bought.

Someone has basterdized the poor thing, lots of rube Goldberg etc.

It will does not run well, has wrong distributor, wrong advance, timing etc.

I can take care of this stuff no issue, but here is what I need from you all.

It was a stick car, converted to PG. I have a 65 RA engine [95 horse] mated to an early diff and it is leaking oil drastically.

Can this conversion be done correctly, and if so, what should I look for, the diff is wet with oil, and it leaks profusely when it does run.

Late engine should have a Late bellhousing, flywheel, pressure plate, throw out bearing and clutch fork pivot.
The input shaft depends on what the transmission accepts. 64 and up transmission has a bigger diameter shaft. The seal in the differential snout should match the input shaft.
Early side shrouding pretty much fits on a Late engine.
64 only engine mount bracket is desired to clear harmonic balancer but you might be okay with 63 and earlier with a solid pulley on 95 HP.
Differential side seals are a common place to leak. Sometimes a new seal doesn't do it because the yoke is loose with axial play.
Leaks when it's running can be several different things.
Hope this helps and I'm sure others will add things.

Sounds like it should go to Minnesota - or Kansas City, and get fixed.

Bob: are saying the engine in the 63 is the RA 95HP?

It is installed on the early PG transaxle?

Are you leaking diff lube or Type A when running?

Or is engine leaking oil when running?

Probably has an early Bellhousing that put the engine's "front MainSeal" in the wrong place..... if leaking engine oil..

I am going to have to get into this thing deeper.

When I learn more I will seek some more advice.

It has been a while since I have seen such modern mechanics.

Steve:

The car is a 63.
The engine is coded RA, which makes it a 65 95 HP.

It is mated to an early diff, with a brand new PG on the front.
