Hello all, I have a buddy looking at an 86 4KCSQ for sale. It needs new lifters but other than the a/c having a leak and needing very little else (cruise control) it is in good condition. Any pointers on what to look for? Lock the diffs? I honestly have never driven a quattro. The closest thing was a 91 C4 cab. TIA, Rich Andrews rjandrew@post.cis.smu.edu
