Op, there's a company in Canada Whitehead Performance that sells parts for the r230 swap. Just yesterday I got their shortened axle shafts from Moser, their 39 spline stub axles and companion flanges. When ordering these parts from them be ready to wait a while. The drop mounts, moustache bar, front diff mount and sway bar were from TTT and they look great, almost a shame to mount em behind the fuel tank. My only problem now is finding the q45 or 300zxtt cv axles to finish building the cvs for the z aside remans from oreillys. Good luck if you decide to do the swap, like anything modding datsuns it's gonna cost $$$$
