hello from New Zealand, 18 spline head ache a833.

With the look of the input, and 18 spline, and has Liberty modified gears and no synchros, it's probably an old box from someone's MP Chevy race car or something similar. I bought a couple used years ago from a Chevy guy; they even used them in Chevy Pro Stock for a short time until Lencos. Tossed the input shafts they came with and put Chrysler ones back in them to use in my Dodge.

that does make sense,

i spoke to brewers and its a 1000-1500$ job to get it sorted

whats MP chevy ?

im 99% sure it has a red stripe liberty gear set in it

where did you get the chrysler input shafts from ?
