With all your help and a call to Marlin, I think I got this figured out.
I did get real lucky, it is a R151F. Not sure what it looks like inside yet. Got my fingers crossed.
I can use my 21 spline t-case shifter and base but not my W56B shifter or base.
I can use my existing clutch and flywheel. The turbo is different but I'm told mine will work.
The output flanges have a different bolt pattern for the drive shafts. I can either swap mine over from my 21 spline case or get the multi bolt pattern type.
Still not sure about any switches or wiring. Probably not a big deal.
Thanks for the help! All I need is a turb trans shifter base.
