Default Which diff do I have?

How do I tell if my diff is a 44 or a 36?

I have an '88 vert 4+3 w/3.07 gears

The top diff is a Dana 44. Two bolts at the top. The Dana 36 has three bolts at the top.

Unless someone has been there and swapped it out with a D36, you have a D44. All 85+96 manual transmission Vettes had the D44.

Maybe 3 cutouts on the 44 and 4 cutouts on each side on the 36 would be a little less confusing.

But I'm running 371HP and 450 ft.lbs. of torque to my 36 and no probs so I really don't think it matters one way or the other.
