Exactly what companies sell the chromoly axles?

Do you have any extra info on the HKS or Guru transmissions and what prices would be?

Nice to see some options for when I build a TII.

 

um....you should really do some searching on that....it's not too hard to find. I don't know off the top of my head.

After finding out some further info, the axles should be interchangeable, but i'm wondering what half-shafts i need for the miata torsen into an S5 diff housing?

 

Worst case, I would think you could find a local drive axle shop to take the inner joint from a Miata halfshaft and the outer from your existing driveshafts and make a new set for $45 if you bring them both sets of axles. You might even luck out and find it's the same diameter and spline count on the inside or outside and you can use the whole thing.
I know it's been done before, but that seemed like a lot of trouble for not a great deal of improvement, so I didn't read on it alot, figuring I could come and find the info later if a Miata LSD landed in my lap one day or something.
