Dellman,
It's from a car but it will work just fine in a truck. Install some longer 1/2" bolts with nuts on the truck. If everything else looks OK, use the side cover and bearing retainer from your existing trans. Install a new seal and you are good to go.
Drew, If both of the transmissions you are referring to have the 4 bolt side cover, all the transmission parts will work with the OD trans. If one of them has the 7 bolt side cover, none of the trans parts can be used in the other. Note: The only part of the trans that is B/W is the OD portion, the front half is GM.
