Well I have the same 59 /292 sitting in my shop with thr heavy duty 3 speed on it and was thinking the same thing as I have a 56 passenger car overdrive in another car . the difference I saw was the heavy duty 3 speed has o bigger input shaft and it is about 3/8 of an inch longer . I thought I could just use a smaller passenger car clutch and throwout bearing along with a car clutch arm . In my project I would just get a drive line shop make me a new driveshaft . Thats all I can help you with , maybe somebody will come along and help both of us .

I don't think the input will reach to the pilot bearing, but I'm really not familiar with Late Model stuff. To be honest, if I had your setup, I'd be doing a T5 swap; much better tranny, just have to work out the shifter.

the car/truck OD's are the same, there are three models R9, R10, R11 with the R11 being the newest and the strongest (4 sun gears).
The trans mission has to be made/adapeted for the OD unit - there is an extra hole in the rear side of the tranny that allows the reverse lockout to operate.
Then you need to round up the electrics and hook it all up.
You may need to modify uour drive shaft.

Swapping the input shaft is not that hard, although on some 3-sp's you have to drop the cluster gear to get it out. But like I said earlier, the key is whether the main gear has the same number of teeth in a car and truck tranny. To do it really right, you could get a truck 3-sp and swap everything into the OD's case, using the OD main shaft, and all the gears from the truck tranny. As Dick said, the case for OD's has the extra hole, and the main shaft is the only other difference compared to a truck OD.
