have a 392/518 in my 58 Plymouth. Pat @ A&A did the trans and it works great. The car has 4.10's in it and the o/d unit has been flawless so far in wide open 3-"4" shifts and where I stayed in it in o/d under wide open blasts. The shaft with the oil holes for o'd lube were opened up to 3/16 for increased oiling. Mine is a one wire, I have a push/pull off/on button where the shift quadrant was and a floor shift. The o/d unit fits in the recess for the parking drum like a glove on my car.
Excellent, i was thinking there would be plenty of room for the OD unit since the OE trans had that parking drum hanging off the trans. You have a picture of the trans crossmember mods that were needed by chance?
