Will a 1955 3 spd OD fit my truck? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey Fellas, I’m trying to do research, I found a good deal on a 1955 3 Speed Overdrive that I was told that came out of a Bel Air.
Would this Transmission fit into my 235 straight 6? My 235 I believe is a 1957 based on the serial number. And my truck is a 1961 Apache.
What modification am I going to need to do?
So far what I have found that I may need to shorten my drive and possibly change the input shaft depending on the size of the tranny?
