833 Id?

Trying to figure out what this one is. P833 5624. On the tail shaft is C13386, just below it is LA. On the case is C13303A, 10.21.76. and a 23 spline shaft. I'm not really familiar with the four speeds but the shift rods look extremely big and the tranny mount is some contraption I've never seen. It's a short shaft, looks like an a-body but now I'm not sure. Any help much appreciated.
