Ok here's thought

You can put a 12bolt diff in a C3 Corvette center section.

Tom's differential has all the parts can can build 7 seccond NHRA legal setup.

A Bulletproof '63-'79 Corvette IRS Setup That's NHRA-Legal To 7.50S
http://hotrod.automotive.com/79266/05 ... ette-irs-setup/index.html

I was at a Corvette shop last night and measured up a C3 diff, which was very similar with wise.

I know people make adapters to go from a D36 to a D44.

I'm wondering if I can make one to go from a D44 (or a D36) to a C3

thought?

with any amount of welding, sure, anything will fit anything... but I feel the D44 is better than the 12 bolt.

I prefer the Ford 9" if you want to go drag racing. But for road racing, I would just get the D44 built right and be done with it.

I don't see why not; but would you not use only the modified 12 bolt C3 center with the C4 spindles and dogbones?

Other than the weak clutch packs, laughable aluminum housing, smaller ring gear size, and axle design that breaks under wheel hop the dana44 is great.

Oh.. dang.. my bad.

Then why go through the effort of retrofitting ANYTHING?

I keep forgetting he does that road course stuff.
