    What are some good reasonably priced overdrives that will work on a model A? I know of the mitchell overdrive kit and the Columbia 2 speed rear end, but what are some others?

    Go over to "The Ford Barn" site and either search for Model A O.D.s or post an inquiry on the Model A page. There's a guy in Ohio who adapts B-W R-10s to a Model A driveshaft and eliminates the electrics. Since it goes right in the middle of the driveshaft/torque tube, it's not obvious.

    Check out this guy:

    Really good solution--really not cheap--2900bucks.

    It's a Ford T-170 trans--3speed with overdrive--converted to a bolt-in for stock A drivetrains. It may be a more complex install than a Mitchell Overdrive but it's full syncro and is also available for V8 cars.

    '40-48 Lincoln OD trans...normal V8 engine/torque tube flanges. Stock, it will have one of the close ratio gearsets, 25 or 26 tooth, and about .7 OD, meant to be used with 4.44 gears for best results. Requires substantial driveshaft shortening.
    Lots of people have been looking at T5's with four-wheel-drive tail, which offers a nice flat place that might just accept a Ford TT U-Joint housing casting...
    That might well prove a good way.

    I have a friend in Texas that builds a kit with the topshifted toploader aluminum 4 speed as the heart. They do a lot of machine work so you don't have to hack the cross member. He gets around 2700 and that includes the shortened driveshafr/tube and everything else you need.

    I had a chance to visit Dave at his house this past weekend and picked up one of his Weber Kits. One of the nicest people I have meet and i could have spent the whole afternoon talking with him (never felt like he was rushing me out). The quality of his work is some of the best I have seen, and he has a wealth of knowledge. I look forward to getting some more of his products.

    My wife bought a 29 Model A with a dual stick transmission. I drove it and the second stick is an overdrive. I can't find any information about this. I'll have to crawl underneath it to get a better look but it is attached to the original transmission and the torque tube is attached to the other side.

    Does anybody have any idea what kind of overdrive that is? AA?

    I have a Borg Warner in my two door that works well, from a '50's stude I think. But the
    T5 from an S10 is what I'm going to put in my '31. A kit is available for 895.00, includes
    everything except the trans. Auto Restorations
