Also, was on your profile and saw the rendering for an extended cab truck. Any progress??? I am dying to do a 4-door 58 with a big flat bed. I would love it. The rendering for the extended cab looks awesome!
sorry for the slow reply, not sure why I didn't catch that question earlier when I replied about the mirrors! No progress on the extended cab, probably still a couple years about before I start on it. I am working on drivetrain on the 58 and also my travel trailer that I pull with the truck. I don't get as much time to work on stuff as I would like (or I am too lazy!).
So I finally got the front end kind of built. Made a transmission bracket and installed the shock towers.
My next step is to find a power steering box and then figure out the mounting and drag link. Then I can figure out where I have room to install the Panhard bar. It is really tough to find room for the pan hard bar. I am struggling with that right now.
I am buying an International Scout steering gearbox and a 1977 ford F-150 4x4 steering gearbox to do some test fitments to figure out what will fit best.
Scout steering box has Pitman arm fwd of the box. If it is turned around, wrong way steering, place in Texas can change gears to correct way. Ford might work. GM box (Blazer, etc.) mounted as far fwd with the arm aft might work. Arms can be moved from side to side to for and aft by filing away the skip spline(s) on the output shaft, good ball game project.
'37 GMC T-18 w/ DD 4-53T, RTO-610, 6231 aux., '95 GMC running gear, full disc brakes, power steering, 22.5 wheels and tires. '47 GMC 1 ton w/ 302, NP-540, 4wd, full width Blazer front axle. '54 GMC 630 w/ 503 gasser, 5 speed, ex fire truck, shortened WB 4', install 8' bed.
So I bought the Scout box and it did not work. Luckily, the guy I purchased it from also had an F-150 steering box as well. Out of a 1977 4x4 truck. I mocked it up, and it looks pretty good. But I am no expert on steering so not sure if the pitman arm is too far forwards.
Does anyone have any thoughts?
(If I use the ford box, I will have to grind off the ford logo on the casting)
Assuming that the axle is at "normal" ride height and you intend for the drag link to go across to the right side under the vehicle, it looks to me like there is a long vertical distance between the box and the tie rod. That would cause bump steer that could be objectionable. As the axle comes up in a bump, the drag link will push the tie rod to the right, as it falls it will pull the tie rod to the left. They all do it to differing degrees and you do need some clearance. Just my thoughts.
I will try to get a look at my '62 and see how it is set up, it has been a very long time since I did it. I used a box from a Chev pickup and the drag link goes rearward to the top of the left steering knuckle, nearly parallel with the ground. There is enough room in that one so the linkage does not interfere with the tire/wheel.

Yes, I am aware of bump steer. It can be eliminated or minimized based off of the design of the pan hard bar. I have not installed a pan hard yet, waiting for the steering to be squared away first. I appreciate the input!
