JJL what your saying makes more sense to me. That the 88 is a standard/wheatland/western version of the 85.
I read something that said the 88 was a diesel version of the 85 but I knew that wasn't true. Being in Mich I can see why I have never seen a 88.
My 85 has spin out rear wheels, adjustable front axle, 3pt, 18.4x30 rears, clam shell fenders, and a pto.
I have seen pics of 85's with an aluminum strip under the hood (mine has it) and pics with out the strip.
