I am definitely not an expert on Pinto conversions. I had considered one for my ’32 back in the seventies but for several reasons I chose to go with the Chevy II engine. Since I had considered the engine I made mental notes when I saw or read about the conversion. I assume you have a Model A that had a Pinto engine added back in the seventies or eighties using the original Model A transmission and you want a better transmission. I believe they make an adapter to add a ’32-’39 transmission to a Model A engine but I think the adapter is going to turn out to be in the same location as your current adapter between the Pinto engine and the Model A transmission so you won’t be able to use it. Call Clings [(480) 777-1202)] about the adapter but I am fairly certain it won’t do what you need. You might look into converting the current Model A transmission to synchromesh using the kit from Mitchell but be sure to read reports on it on Fordbarn. You could then add one of their overdrive units and change to lower rear end gears. Remember if you replace the Model A transmission with a ’32-’39 transmission you will need to fabricate brackets to mount the brake and clutch pedals (again, Cling’s may have a kit). To answer one of your other questions, yes a ’32 to ’39 transmission will bolt to a Model A Torque tube. Best of luck.
