yes,use a 86 3/4 ton small vac booster or do a plate for manual brakes
change wire harnes to an 85 so it can be worked and have the VR for charging.
one side of frame may not let you boult a BB in,mine would not,so I swaped to 85 frame along with 85 harness for my 88 truck.
you need the BB 727 short shaft that has the 4x4 output shaft and the trans to xfer adaptor which has the tall mount built in,you need the 4x4 xmember also
if you use a motor plate bolt the tranz up in stock location and set the engine/frame/plate
