I have a 140k miles 4.3:1 Torsen Differential. No noise, no known issues, 10-20k miles at around 220whp, less than 10k miles at 300+whp.

I'm looking for any open differential from a 1.8l Miata plus cash. Open to negotiate, but I'm looking for around $700 on top of the trade. Due to the fact that shipping the differential is going to be expensive and possibly break ****, I'm very strongly wanting to do local only.

I'm located in Northeast Tennessee (Johnson City/Kingsport/Bristol), but I frequently travel to Knoxville, Nashville, Atlanta, and Charlotte. I'm rebuilding the differential (new R&P and OS Giken) so mileage isn't a huge issue as long as it is reasonable.
