While researching Rb swaps I came across this piece of tech info, so Ill cut and paste it here in case it gets lost for people searching the same, Gtr, gts4, GT-FOUR and stagea should all be the same parts numbers Do the reverse of what this person did Quote from: https://www.skylineowners.com/forum...ns/208381-my-r32-gtr-rwd-conversion-hubs.html So I picked up a r32 gtr that was previously a rwd 1400 hp drag car. It had ran a rb26 then a 2jz infront of a chevy powerglide trans. Anyhow ive been converting it back to a full interior rb streey car but rwd. Because everything 4wd related besides the atessa pump has been removed as well as abs and hicas. So I didnt have front axles when I got the shell and I only needed the outter portions to support the bearing... however I could not find a beat set or a cheap set anywhere. So I went with another route I heard heard about but couldn't confirm. I picked up a used set of complete z32 knuckles and pressed hub out from those. And pressed out the hub and bearing from the r32 gtr knuckle. We confirmed the outer diameter and width of the bearings were the same. So we used a new z32 bearing and front seal along with the z32 hub and pressed it all into the gtr knuckle. The issue on the backside is the z32 hub washer is abs related and very thick and would damage the rear seal. So I found some r33 hub washers off a non abs gts25t and used them with the r32 rear seal and it was a perfect fit. The only thing I need to do is make a dust cover. Z32 and r33s are too small but I plan on just spot welding a cover on the rear and sealing it with a silicone . Now abs wont work but I did this all for a total of 100usd including the new bearings. So to confirm you can turn r32gtr knuckles to support rwd and the bearings without using axles from a z32. Z32 hub Z32 wheel bearing R32 gtr knuckle Z32 feont seal R32 gtr rear seal R33 gtst or s14 front hub washer Wont use abs End quote.
