Guys i have a borg warner 4 speed with following markings

13-04-066-906
13-04-065-903 W.G. DIV Fc
6.26.81
MLT5819

26 spline input AND output im certain i counted.

6 dash input splines

any help on what rig this is out of? Need driveshaft end

 

I don't think they made a 26 spline output. They did make for 1982 a 27 spline output (TH350), compared to all the other Super T10s with 32 spline outs. That's line up with your date code. I believe 3rd gen camaro. 6 ribs looks like 3.42 1st gear, which is weak.

 

Does it have the torque arm linkage? If so, you'll need to be creative to get a shifter to work with it.
