Ok, I have S14 with an open Diff and I am in the process of swapping in a Q45 Diff. I've already pulled it out and swapped the covers. I have the driverside Q45 half shaft, but I am running into problems sourcing the 90 - 96 300zx TT driverside halfshaft. I've checked at the local parts stores and Autozone which usually has them says their vendor is out of stock and they have no idea if they will ever be restocked.
I might have found them at another local parts shop, but I have to know if there is a difference between the Auto and Manual half shafts on the 300zx TT. I wouldn't imagine there is, but then again the must be a reason for them asking. Any ideas, or other suggestions.
