the only problem with some mags, is fitting them on the hubs, you may need to enlarge the centre hole of the rims to fit on the hub, i have had to do it quite a few times myself, and before you buy mags make sure you can get hubs to suit the stud pattern, as there are limited stud patterns available, but skyline studs are the same as ford so you wont have a problem with those.
also i have a set of stock R32 mags laying around if you want to make an offer?
