I've got an 86 4runner with a freshly rebuilt 22RE. It currently has a G series transmission in it that works but is screaming loudly for a rebuild so I need to do something else. I would love to find a R151F for that little extra bit of strength, but so far they look to be scarce and pricey. In my looking around I happened to notice that the W59 is also a 23 spline output, and with a Marlin adapter can work with a gear drive transfercase. Does that sound like a reasonable substitute if I'm only ever going to have a 22RE or maybe years away a 3RZ?

Thanks,
Ron
