Well i broke my diff . But im seein all these lsd s for $250 to $500 online. Will they fit on my gs car cuz i heard gsl axles and gs are diff plus the 4x110 vs the 4x114. I really dont want to buy all them parts is there any lds pinion that i can install on my car n have it running. Really dont want to take out a whole diff.

Any diff from an '84- up 7" will work, including nonturbo FC and 1.8l Miata.


edit: Honda S2000 diffs will not work, they are 29 spline.

​​​​​​All GSL rear ends are 4x110.....so any year GSL will work on your GS.....and with disc brakes and LSD.....

Not quite.

If you want a DIFF, then any 26 spline diff from a 7" will work. Mazda changed the spline count from 24 spline to 26 spline for MY1984. So this means diffs from any '84-85, any nonturbo FC (except VLSD because of weirdness), any 1.8l Miata, the front of Mazda pickups and Kia Sportages (rears were 7.5" or 8" depending), and apparently Mazda G-box front wheel drives (Protege, Escort, maybe some 626/MX-6/Probe) but I have not confirmed that.

If you want a COMPLETE REAREND ASSEMBLY, you need a '83-85 rearend for a bolt in. '82 and earlier had a different driveshaft flange, so you would need a different driveshaft or swap the flange.

Incidentally, a 1.8 Miata pumpkin will bolt in and is the right length, but the flange is FC N/A sized. Just to be weird, the 6" from the 1.6 Miata used a '83-85 type flange.


You have to be mindful that ROW went to 4x4.5 bolt pattern for ALL Series 3s. North America was the only market to keep 4x110. Also the only market with rear drum brakes. So, there is what may appear to be contradictory information out there if you don't factor in where the info is coming from.
