    To get less turns lock to lock you would have to lengthen the pitman arm
    FWIW, that was a 1960s Stude racer trick; cut one at the bottom and one at the top and weld together. The '56 Power Hawk I drove from 1970-95 had a lengthened Pittman arm and it did steer a bit heavier, but I was young and strong. That steering box and arm is still around the shop somewhere.

    If you can find it back I think a picture would be interesting.

    BTW - These are what I bought for doing the EPAS on my Sky Hawk... $88... https://www.ebay.com/itm/09-10-11-12...xYJJj7&vxp=mtr and this https://www.ebay.com/itm/09-10-2009-...!US!-1&vxp=mtr

    I researched different EPAS systems, and with the controller, the Toyota Corolla is, by far the least complicated to hook up...3 wires only...power, ground, and ignition on...https://www.youtube.com/watch?v=f4TYQ_KJSpc

    JACK - Do you remember the length...LOA or center to center, of that lengthened Pitman Arm?

    No, but I'll try to remember to measure it if I can remember to find it :>)

    Now I'm starting to sound like another guy on this forum that thinks anyone that wants more that 175 HP must be crazy. Why would anyone need a car that would run more than 60 MPH. <G>
    You're exactly right Jerry~! Driving my '55 President coupe down the road was never a problem. Parking, getting in and out of the driveway, and maneuvering in small spaces was agony. Other than lack of power steering and a/c that 67,000 mile car was my favorite of all the classics I've owned over the years. Regarding HP, the 259 V-8 with a properly tuned WCFB was more than adequate. Floor boarding it at 45mph when the secondaries opened was surprisingly strong. The mega-HP engines being produced today are downright stupid, unless you have a powerful desire to lose you license. Back in the late '50's and '60's when you didn't see a cop every 3 minutes, we might have been able to enjoy something like that on rare occasions.

The distance at the back of the cross member between control arm mounts is so small it doesn't leave enough room to get 6 plus inches of travel, and clear the oil pan at the same time. If someone uses an electric rack with center steer I might try it. Looked into a used Ford Taurus police rack (rear steer to get the rack motion correct) and using a traveling bar, but won't fit. Oh well, just have to live with the Bendix bag of snakes for now.
    Why not go 'balls to the wall' and install a Fat Man front clip? You can pick up five improvements at once, disk brakes, modern control arms, ball joints, rack 'n pinion steering (poweer or non-power), and correct Ackerman~!

    Jerry - Where did you get the round piece, in the fire wall, that the steering shaft is going through?...

    The outer shell is the original mast jacket. I machined the solid steel insert and pressed an oilite bushing into it.

    Thanks, Jerry. I'm having an extra Bell Crank Steering Arm shortened an 1 1/4" and re-welded. That way, when I get home in the spring, it'll be ready to swap with my Stock one. Between the shortened Steering Arm and EPAS, the steering effort and lock-to-lock should be just about right. I'm getting just to old to handle the Stock manual steering anymore...

    Tony, so far, the only thing I would have done differently is make the upper column 1/2" longer and move the EPAS unit 1/2" closer to the firewall. Where the turn signal wires and horn wire come out of the column I just barely have room for a gromet at the original Studebaker column hanger.

    Jerry - Just about where, on your bell crank, did you take out the 1" to shorten it?

    About 2" from where the drag link attaches.
    I just rechecked the lock to lock and it is 3 3/4 turns lock to lock.
