A friend of mine is wanting to get rid of some old engine/trans adaptors and he wants to make sure he can advertise them correctly. No casting numbers or logos. Thanks for your time.
We can guess all day long...photos from the side and back would be helpful as would some form of measurement across the block face.
The first picture looks like a Packard transmission to a Chevrolet engine. The other two….??? The starter recess is on the p***enger side - Buick, Pontiac, Olds, Chrysler are on the driver’s side. Some adapters may have relocated the starter. The one below it looks like a Chevy transmission to maybe a Ford engine (Y block, FE, MEL?) The third one looks like an early-mid 50s Ford truck 3 spd to a Ford engine (FE, MEL?) The 2 bolt clutch pivot says Ford to me. BUT, both have a starter recess that’s on the correct side but too small for the funky backwards Ford Bendix and maybe a little low. The Chevy pattern is easy, but the other two aren’t. Someone on here can probably tell the Ford bellhousing patterns apart, I can’t. Unlike today, there were a whole lot of adapters made back in the old days, some were real oddball combinations. @Black Panther might be able to help. Like 73RR said, we can guess all day long.
They all have numbers someplace. They all look like Trans Dapt units. They all look like they're Chevy. The bottom two appear to be the kind that use the cast iron starter adapter plate. See if you can find the numbers and ill look at my catalogs..
Yes, Trans Dapt did you a favor and cast the part number on their adapters. #1 looks like Chevy to Studebaker three speed to me. #2 and #3 look like the style of adapter that, in turn, bolts to a 1955-62 Chevrolet cast iron Powerglide adapter.
