r33/32 all use an r200 diff (meaning 200mm crownwheel)
As long as as the crownwheel and pinion are from a r200 diff then all ratios are interchangeable.
There are heaps of r200 ratios available 3.69, 3.9, 4.11, 4.3 and more...
AS for the 3.69, u need the cw&p from s13's as they run r200's (3.69 auto 3.9 manual)
