Just getting around to swapping my 360 into my 87 D150 and found out the trans is a 904.I didn't think they put them in full size pickups?Has anyone seen this before?1987 D150 318 2bbl 2wd with an 8.25 rear end.

I know this could have been swapped.I am disappointed as we are ready to drop it in and my 727 stall converter isn't going to work.
