Just recently broke my rear end. Looking into diff replacements locally at junkyards. I've found 2 convertible fc's 88 and 89. Called a dealership with the vin numbers and had them look on their computers to tell me which diff the cars have installed. Both open diffs.

Question is, can I use the pumpkin from either of them on my 97 na 1.8??
I'm looking to get my car running right now, I can always hunt for the fc's internals another time.
I don't know if the rx-7's were turbo'd before, no engines in their bay.

If you post your location, someone near you may be able to help with a rear.

so just buy the aluminum part and replace yours...

 

What were you doin to cause it to break like that?

Should think about doin the bushings while its apart too.

 

The differential I bought years ago from a wrecker was broken like that and they just welded it up. 8 years later and it's still fine.

 

Stealership wants $900 for a new one, so that's out of the picture.

I called around and no one would dare weld it, fear of being responsible if it breaks and I die.

the 88 convertible rx7's open diff pumpkin measures to be the same as my na 1.8's open diff.

____will it hold my internals though?

 

your pumpkin will bolt onto the rx7 aluminum half. You'll just have to replace the bushings with miata ones.

Just replace what's broken and get on with your life for $50.

 

don't you mean my ring and pinion half will bolt onto the housing?
