DANA 36 vs DANA 44
The C-4 Dana 36 was the only axle available in 1984 Corvettes. In 1985, Chevrolet brought out the Dana 44 which was similar to the 80-82 Corvette axle, but not interchangeable. The Dana 44 axle is considerably stronger, but not indestructible. The Dana 36 and the Dana 44 (44's in some autos and all manuals) axles were used through 1996.
The Dana 44 is much larger than the D36. The 44 has a larger, "beefier" carrier/components to handle larger (lower) ring and pinions, and increased torque. NOTICE THE LOCATION OF THE TOP CENTER BOLT HOLE ON THE DANA 36 THATS NOT ON THE DANA 44 REAR, thats a QUICK WAY TO TELL THEM APART

Look at the size difference, especially at the case above the yokes:

Dana has also supplied the Viper diff since '92, and since '96 it's been the Dana "Super 44", specific to the Viper application, with larger bearings and a unique carrier and yokes to handle 535 ft-lbs. of torque and a 14"-wide tire contact patch.

From reading this post I think it may be possible I have a D44 on my 89 auto.
I can't get a good look at the top of the diff. Is there another way to find out if the diff is a 36 or 44 ?
TIA

Dana 44's are good for jeep rock crawlin.'
