I have an 81 PuP..Chevy LUV. 5 Sped, 2.2 diesle. Ilove it. One thing tonote is the frame and body rust.
The frames are, unfortunately, famous for very very bad rusting. So far I have welded up over 60% of mine back together.
Aside fromt hat they are a tough littel turck, just the right size for most anything. Note the max payload is in the area of 1100 pounds.
Use engine oil in the tranny...not gear oil and never overspeed the engien. 3500 is redline.
I hve 220K on mive and wouldn't trade it for anything (except an identicle brand new one!!)
Enjoy.
