What is the diameter of 94-95 Miata stub axles?
That's what I need to know!! Here's why. I am in the middle of rebuilding an RX7 LSD and ran into a problem. I pulled the LSD from an 85 RX7, which should work right? Well, I got some axle stubs that are supposedly 86-91 non-turbo RX7 stubs, but they are too large for the diff! So either these aren't the correct axles, or somehow I got an 85 RX7 LSD that uses smaller axles.
I measured the RX7 axle stubs and they are 27mm. So if Miata stub axles are 27mm as well, then I'll need to find a different diff. Which would make me sad because I'm ready to get this thing in there. Plus I just spent a bunch of money on some new parts from MazdaTrix.
Also, if Miata axles are 27mm then that means all of the FAQ and info pages on RX7 differentials are incorrect. Everything I read (and I literally read everything on this subject) says that the 85 RX7 LSD will work. I know for sure that this diff came from an 85, I pulled it myself.
Here's my problem, I'm seriously pissed off about this, I was ready to install this thing tomorrow and now I'm going to have to wait and figure this out. Damn.
Here's the 86-91 RX7 stubs that don't go into the 85 diff...
And some other pics of the diff...
So do I need to buy a new diff or what?
