Correction on the flywheels. One is 7MZ the other is 3PX, NOT 3MZ. The complete numbers on each are:
037000-2641 7MZ
037000-3322 3PX

037000-2641 7MZ is MC21 (I just happen to have one here on my desk!)

Andy are you saying that the pickup coils for R4J and R5K are interchangeable as long as the flywheel is the correct size?

No. The pickup coils are different. They could possibly be modified to fit though. You'd be better off with the correct parts though, as their positioning from the flywheel is pretty critical.

Also what is the timing issue with the flywheel/rotor? Just asking because I do have offset keys from Tyga which will advance the timing 1-4 degrees.

That you'll have to figure out on the dyno. I've never bothered with offset keys myself.
