Hey guys, I have a miata and swapped a first gen RX-7 LSD into it and am having a problem with my axles wobbling about a quarter inch in any direction except for in and out, they seem to sit in the diff very snug. Does anyone know what this could be?

Does anyone know what the spline diameters are for the different non-turbo models of the first gens?

All help is greatly appreciated, I'm very lost here.
Thanks.

 

which one did you use? 81-82 or 83-85.
