I have acquired a 3 spd overdrive from a 1955 that I'd like to install. I have a new open rear end. My original engine had been replaced with a later model 250 with side mounts replacing what I assume were front and rear engine mounts. The new tranny does not have any obvious mounting flange, but I am guessing it needs more support. Do I need to find a bell housing that will provide rear engine support and leave the tranny hanging or do I need a rear trans mount? | | |

There is no mount on the back of the tranny. On my 72 truck there is a brace on the 700r4 automatic. It doesn't need anything else. That's all in there pretty solid. | | |
