Looking in the 1965 chassis shop manual, page 4-10, figure 17 - the carrier is broken down in sub-picture item 41. Item E is the yoke retaining nut. Is it as simple as removing that nut to make this an early style floating yoke set up?

Probably not, Greg. The late model differential internal carrier is wider than the early model one. That’s why folks like Ken Hand machine them down 1/4” to fit in early model diffs. I have wondered about whether the nut would make a difference and I think it would be better to remove them due to rattling around until they chipped or damaged the spider gears. Even if you remove the diff chunk to machine down the bearing bosses, does the case have early side adjusters or late adjusters? That is also a different part early to late and could interfere.

Autobahn makes a good looking product but I always notice they assemble the head on the wrong side of the engine for the vacuum tube to fit.

Steve has another setback on this one.

On the original post, that is a 1960 differential chunk and does not use a longer left side. Unfortunate situation that OP was so frustrated to read that there was nothing wrong with it. Keeping thingS original can be frustrating and expensive. To me, that design is superior but Chevrolet redesigned it. More efficient to make two different length yokes than two different precision machined spider gears.

Plot thickens.

This is an early carrier.

Possible to out late model yoke nut in early carrier?

I’ll disassemble soon and post findings.

Extracted the culprit the AM.

Diff is back together . . . third power pack install is a charm (I hope) . . .





LH yoke seats correctly now:


A little clean up, governor drive and shims and a top cover gasket and we are in business.
