I have an 85 Z28. I would like to put 16 or 17 x 8 all the way around. Due to $ I am trying to dig up some from another chevy (vette or other model camaro/firebird etc) out of my local junkyard. I have a huge one in S. MD with a monster selection of GM wheels but I am not sure what to look for. Also does this size require any spacers?

 

i got 16's off of an '88 WS6 formula on my car and they were a direct swap.

 

The easiest way would be to find some 16x8 3rd gen camaro wheels. I like the first style Iroc wheels, so I got a set of 87 Iroc wheels. Any third-gen wheel will be a bolt on installation with no spacers required.
