blacktop, i was at taylors today he looked at the diff sadly its open. i pulled it off a wrecked gts which also had the blacktop 20v im swapping. I finally found a harness and taylor said megasquirt was ordered. I just switched suspension set ups, from megan springs and kyb gr2's to kyb agx and swift 6/4 springs. ive only installed the back so far. its good to hear from another local 86er, what you running?
