A833 18 spline 4 speed crash box.
Some were home made by cutting teeth. Here are pics of the bought gears.
I have 4 here and you can see the end one with the rods was cut for a GM.
Driving them on the street was like driving my 53 Chevy with no syncros. If your not pulling a gear flat out you need to double clutch on the up shift and give a burp of the throttle to down shift.
Face plating is much better they shift like a motor cycle. Friendlier on the street.
