anyone knows where i can find a set of 488 ring and pinion for my 85 rx thanks

 

I've heard a cheap upgrade is to use the gearset from the late '80s to early 1990's B2600 4X4 pickup , though I thought they used a 4.625 or 4.44 ratio. Anybody out there know the exact ratio ? That would get you close and used/wrecked pick-ups are all around now.I actually used the ring and pinion from a late 90's Miata (4.44)and built it with my FB LSD...its great.Hope this helps.....RR
