Default Is this a D44 or D36

According to the seller it has the 2 bolts on top which would be a D44 but I was hoping someone might be able to tell from the pics.

When advertised correct on Ebay or elsewhere,
These C3 dana 44's are a deal to pick up $ Cheap for a street rodder.
Low as $100 complete with brake rotors & calipers.
Just have drive to pick them up.

C4 Dana 44 prices are very high yet for the desirable 3.45 & 3.54 factory installed rears. $1400 to $2K.
Used. Take your chances using it in your car as is.
Some sales I have seen did not include the batwing cover.

No one wants to budge off their prices for them.

1985- 1987 C4 3.07 : 1 rear diffs can be bought for $900 to $1,100 with some searching.
Batwing cover included.

Have money left over to purchase New ring & pinion set & installation kit then.
Get the 3.54 to 4.88 gear ratio set you want then.
Be money ahead & freshly rebuilt too.

For future reference if you are looking to buy.
C4 diffs ( both types ) have alum halfshafts , a fiberglass spring and have a bracket each side underneath to mount the camber arms;
not the one piece bracket shown in your pic

This guy is selling it for $200. When I called he said he received the rear end in lieu of a debt and didn't know what it came out of although his clearly says 1986 Corvette. I thought if it turned out to be a D44 what a deal. I wasn't thinking about it being a C3.

Thanks for the help.

Yeah I noticed the multi leaf spring, but only after I had posted. Wasn't thinking about the half shafts being steel either, one of those times when you look back and say, "I knew that".

Again, thanks for the help.
