recently my rear end died on my 82 s. after many tries to unsuccessfully start my other 7 ( thread about this is here https://www.rx7club.com/1st-generation-specific-1979-1985-18/need-help-no-start-condition-668715/ ) i located a rear end. it came off of an 83 GS (not mine ) and has large axles, but is still open diff. i will be using this rear end for a while but my question was this...since it has the large axles could i possibly use an LSD pumpkin on it and keep my drum brakes? i know it would be more feasable to just pull a rear end that has the disc brakes but i was just wondering if it could be done.

 

As long as the axles are the same, the pumpkin can be swapped. Big axles also allow the use of Miata diffs.

 

thanks
