Gm used a version of the A833 in some pickups that has the same 10 spline 1 1/8 input and the standard gm bellhousing pattern. This version is also sometimes referred to as an MY6 transmission. Several bolters have swapped this incarnation into their bolts. It is a sideshifting transmission and will relocate the shifter from the factory 4 on the floor location.
T5s are more abundant and fairly cheap. If the s10 version doesn't work, you can try making a hybrid from a camaro with the s10 tailhousing, or getting a tremic transmission.
HP will not really be a factor for you, but weight and torque could be. The t5 will likely work well for a light duty 3/4 ton. It would probably not fair to well in 3/4 ton that routinely hauls heavy loads or pulls trailers.
