Borg Warner T-10 ID
 

I have the following 4spd in a 62 Impala which I am restoring. I am trying to ID the transmission and would appreciate any help. The following numbers are found on the case:

Stamped into the pad 19L524005
8.31.78/1
MLT7802
1204065903
WG Div.
FpC4
Has 3 grooves on the clutch spline.

Thanks!
