Questions on Using A-833 4-speeds in Chevy cars

[troy.70R/T]

I have a few questions reguarding the practice of using A-833 Transmissions in other cars. Let me explain why I am even asking these questions. I have a A-833 A-Body Trans. The input shaft has had about 1 inch cut off of it because it was used in a Chevy car at one time. I want to sell the transmission. I thought about selling it as set up for a chevy car before I spent the money finding a new input shaft and selling back to an A-Body mopar guy. However during my search for an input shaft I had a guy call me and tell me that some Mopar guys cut the end of the shaft off too so that they can use a roller bearing style pilot busing "bearing". He said that this bearing was developed in the 80's and is used because it is better than the pilot bushing. He said it is installed in the bigger (about 1.500 dia) hole at the back of the crank and not the actual pilot bushing location. He said installing this type of roller bearing is why a Mopar guy would need to cut the input shaft down. I would like to know if there is any truth to this because then I could sell it to a Mopar guy too and be able to explain why it is cut down and what they need to do to get it to work in a Mopar. Or at least be able to direct them to a site the explains it to them. Any help guys?

it can be used in mopar v8's with the use of a 92ish Dakota? pilot bushing

i cut the input shaft on my transmission to fit my bigblock mopar because it was never intended to have a manual transmission (no hole drilled for a pilot bushing)

Bottom line, it can still be used in a chrysler car for a auto to 4 speed swap

The bearing/bushing below fits in the crank register originally intended for the converter snout. Best way to deal with a shortened pilot. Mopar part numbers below.

thanks guys. How much shorter can the overall length be? Can I get an origional overall length on what the shaft should be and then a measurement of what one would need to be shortened too ( with a plus or minus tolerance) in order to run those style bearings? I just want to make sure I am not screwing anybody when I tell them it can be used that way. I want to be able to tell them what length it needs to be if it needs to be shortened even more. Thanks again guys you will have made my day if mine will still work for both appliucations without having to buy a new input shaft.

my pilot shaft is only about half an inch long, but im using a viper t-56, but same idea

now according to most a STOCK pilot shaft can be cut down by .5 to .75 of an inch,

to give an idea, this is my viper shaft AFTER i cut .5 of an inch off it, i had to cut ANOTHER .25 to get it to fit



and an old dakota pilot bushing i destroyed
