anyone identify this rearend?

You've got about a 90% chance of it being a Dana 70. I had one on an '84 with left handed threads on the driver's side. Took me forever to figure that one out, and stripped out a few of the lugs when I tried to change the wheels on it (I only had the truck for a week at the time). Anyway, that's what mine ended up being.

My 84 came with a dana 61, 3.55 posi, left handed lugs on the driver's side, but it was a gasser. A diesel 84 should have came with the dana 70.

I've seen it on a couple of front ends, haven't really checked a rear diff for it but the bottom right support web as your looking at the cover could have the model number cast into it.

^^^ this. It sure looks dana. If it is, it should have the model cast into the housing. All of them I've seen did.

Sorry, the webbing thing is for Dana's. Forgot to mention that.

Looks like a 70 to me, the rail where the cover seals on the top and bottom is wider than a 60 so it looks more elongated top to bottom than a 60. The covers do interchange between a 60 and 70 though.

why lh lugs though? all the lugnuts were hard to get off for some reason- po probably didnt realize and jammed them on there- so i'll have to replace some & would rather go with rh if it doesnt matter.

LH lugs originally were used to prevent loosening of the nuts while wheel/axle rotated. Like a LH thread on the engine fan on the water pump...
