As the title says 3.90 FD VLSD R160, diff was originally from an 03 WRX (Jeff's Old Taxi) I had driveline specialists swap in a 3.9 ring/pinion when I did my 6 speed swap. Also had them do a new pinion seal at the same time. The drive shaft is from an automatic 02-07 WRX same length as the 6 speed drive shaft. They are in great working condition and were in my running and driving car only a few days ago. Let's start it at $300 obo for the pair.
