    Search the ID number RAT E1, what I found is it's a Dearborn transmission, meaning it was originally used in a Pontiac... Yes Ford sold transmissions to Pontiac, GM didn't have a decent three speed and Pontiac wanted a good transmission...

    Oops on second look the number may be RAT EL ???

    It's a long tail housing version, you'll need a shorter driveshaft to use it...

    Swaping the main shaft that runs through the center of trans requires total disassembly, not exactly a 15 min job...

    Using a shorter driveshaft would be much easier but because of trans length, you'll probably have to adj pinion angle...

    From what I can find it is a medium duty 3 spd that was used in the broncos. Has bigger synchros, etc with the longer case. It's column shift so if your going to floor shift you'll have to figure that one out. - Matt

    My top loader is also a long tail version having come out of my 72 Gran Torino Sport along with the Cleveland that is in my car - installed it because it is all a matched driveline - I had a driveshaft from a 460 police car cut down to fit - being that mine was stock in 72, it is the RUG code trans

    Four speeds were RUG(early ones HEH), three speeds were RAT... Guessing early three speeds used a different prefix as well...

    I measured the tail section and its 14.5 inches. It that considered a long tail configuration?
