i have another pile of these. all from 93-95 LWB RRC's. These 4.2 ecu's are a nice plug in performance gain for all 3.5 and 3.9 trucks and a MUST if you're building some kind of motor project. i made a deal with another d-90 chap for $135 shipped so im happy to honor the same thing to everyone else on this round.
you can email me to my phone (which is best these days....) firstname.lastname@example.org
