Since you're going to run an electric pump, yep, good to go.

Transmissions would have been A999, ( I don't recall for certain what application might have used the 3 speed, if any, memories are getting fuzzy again) A518 or NVG 4500 if in a 3/4 or one ton. 46RH nomenclature didn't come into use until 1994?
