can you get a posi rear end for an 86 b2000 ??
well, I believe the miata differential will bolt into our trucks' housing- not sure though- karasis? russ d?
I belive what you need is the LSD from a non-turbo 2nd gen RX-7.
You can get a torson or a clutch-type.
Double check the info at
I'm gonna have to bone up on that info too and make the swap myself soon!
Actually, it's the 84-85 RX7 that bolts in.
