Hi all,
Have the ring and pinion out of my 2000 SE's Torsen diff. Swapped these for a longer gear set, my builder said these are in great shape. This is the longest gear set available for US Miatas and this is a cheaper way to upgrade to a 3.9 ratio without buying the whole differential. Would like to get $380 shipped CONUS for these, open to offers.
