Posting for a friend. Came out of 94 2wd Blazer with Vortec 4.3. Worked excellent when removed but its been sitting for 6 months so yuou may want to go thru it just in case. He's looking for $200 obo. PM me if interested. Located in Warren.

 

board this is a great price for a rebuildable core!
For a f-body you would only have to change the tail housing for one with a torque arm mount.

 

I drove the truck it came out of and it worked fine. As for pics it looks like your average run of the mill 4L60E, nothing special but I could give it a spray can rebuild for ya if that what you wanna see I think it had just under 100,000 miles but the guy that owned the truck maintained it real well.

I know it will fit a V8 bolt pattern but I don't think it'll fit the 3800. Might want to ask around just to be sure.
