Steering Question

I've set up a few straight axles in smaller cars, 33 plymouth, 29 model A, etc with really god results and I'm planning on putting a 55-59 chevy 1/2 ton truck axle under my 57. I have a gm 525 box out of a 69 Camaro, pitman arm pointing toward the front, that I was going to use. I was planning on the steering arm in the front and the draglink to the box in the rear. Well then I got to thinking about ackerman with the arm in the front, you'd never get the arms out enough, toward the tire this way. Both my 33 and 29 was in the front and steered and handled amazing so am I thinking wrong here?

On my 51 with my steering arm forward, I had to have the tie rod in the back set to 7 degrees down. This was because i had the steering box in front of the axle.
I found a 58 1/2 ton front axle, drums are on it so the spindles should be good. If I can get the locust tree cut that's growing up through it I'll have extra fire wood.:LOL:

Reversing the kingpin angle is wrong Dave. Just because your drag link and steering box is on the front side it wont change the setup for kingpin angle! Angle should still be 7 degrees back at the top of the kingpins.

I have always used front side steering boxes on my gassers, as I prefer having the steering box out front where it's out of the way. I put the tierod on the backside, and off the bottom side bolts of the spindles. I put a steering arm off the two top side bolts on the passenger side spindle, and connect my drag link to it. Gives the drag link a better flat angle, and everything gets setup just like it is for a typical backside steer except for this change.
Usually have to grind out the keyway on the pitman arm to allow it to be turned 180 degrees for front side steer. But other than that it's an easy change. No affect on Ackerman angles as long as the tierod stays on the backside. On my Austin I run the tierod on the front side and I had to cut and modify the steering arms to move the ends out close to the wheels to get the Ackerman angles corrected. With my Ansen slots I couldn't quite get perfect angles and wheel clearance, but it drives extremely well, so I guess it's good enough.
