You may also look at the 74-7085 rear trans bearing retainer for the trans connection. The U joint housing cap, inner (B4513) inner and the 48-4520A caps outer with 2 required. This is for the toy passenger car trans. If talking about the 73-7006 commercial car type trans for the 60 pickups, then the rear retainer is the same as the 85hp at 78-7085. Have fun with it: Fred A
