Everyone will say lower body onto k member but some dont have picker. I have done it an a 65 both ways, complete and seperated. I would say complete but youll have to raise front at least 6 inches to get trans extension under hump and itlk still ge tight at rad support but it does fit. If you decise to lower motor into mounted trans, remove engine brackets, there is little chance youll line them up mounted, at least in my narrow a case as the trans almost hits tunnel at ride height. Just dropnin, bolt to trans, then mount up brackets. Oops you are running plate, my mistake.
