Hi guys. I'm a newbie at this forum. I just recently bought a turbo II rear and axles for my 87 rx7. My question is how do I tell the difference between the turbo II axles from a regular axles. The axles that cames out of my car is the same thickness as the turbo II axles I just bought. If you can help me tell the difference. What is the thickness of the regular axles and the thickness of the turbo II axles? Any info would be greatly appreciated. Rhanks! Ariel

 

TII and NA half shafts are not interchangeable due to different bolt patterns where they attach to the diff. If they bolt up to your new TII diff, they're TII half shafts. If not, they're from an NA.

 

thanks for the info. Greatly appreciated! Ariel
