Hey all,
I am trying to figure out the rear drive train on my NA. I plan on racing SM next year.
The car is a 1990 Model Year with original rear uprights.
I sourced a Torsen II differential from a 2000 model year. I bought the drive shaft, rear diff with casing, and the one piece style half shaft axles.
I am aware that the NC has 5 mm extra of track width per side, are the axles also 5 mm wider to account for this? Or is this extra 5mm added between the kingpin axis and wheel mounting surface? I have read that the spline diameter and length are the same NA-NC, this is why I am confused. Where was this extra 5 mm put in? I will also need the larger wheel bearing nut correct?
Will these parts I just bought swap directly into my original NA rear uprights and Hubs?
Thanks in advance for the help,
-Z
