I am rebuilding a Columbia from a 46-48 Ford to fit in my 40. All the changes happen on the right (passenger) side housing (bell) . The Columbia housing needs to be shortened 3/4" and the outer end replaced with the end from a stock 40 bell. I am sorting thru 3 possible stock candidates for the best parts and gear ratio. Depending on the condition of your wheel bearing surfaces, I would have them re-sleeved also.
