Notes: I used the 3VZ converter to do my RZ swap, it had the right spline count for the RE trans and the right bolt pattern for the RZ flex plate.
VZ flex plate bolts are larger diameter than the R series, but the same as the RZ's.
This should be obvious but worth mentioning since I see it asked quite a bit. The RE, RZ, VZ and UZ all use different A340 bell housings and have cast in letters designating which, the R/RE has only a R.
