how do you convert a 23 spline to a 21 spline :smack:

84-88' G52/54 (carb) and 85-95' W56 (efi) trans always have a 21 spline output shaft. There are no couplers made to install a larger 23 spline input gear to the back of these trans. :mad:

86-87' R151F (22r turbo) and 88-95' R150F (V6) trans always have 23 spline output shafts and matching 23 spline t/case input gears. There are no couplers made for these trans that adapt to the smaller 21 spline t/case input gear.

Hope this help

Simple, Make the first input of the Marlin box, 21spline to match the output of the trans, and leave the rest of the cases 23 spline.
We call this a MC 07-U21 H/D. As the dual case gets longer, It is getting stronger :biggthumpup: :thumbs:
