Home built rack and pinion+ coilover build.

Here are some pictures with something to go by. The first two photos are of my race car front suspension. You can see that the steering arm is less than 5 inch from center of spindle to tie rod end. I hooked the tape to the far side of the castle nut on the lca. The second photo shows how much room there is with race Wilwoods for proper tie rod location. You can go too far and get too much ackerman angle if you use too long of a rack.
The aluminum square in the next photos shows that my street setup has a steering arm of approximately 4 3/4 inch. I am still thinking 4.5 inch is closer to full turning radius, based on the race car setup. On the race car I have over four turns lock to lock, more than stock. I think the extra steering wheel turns(4 1/4 instead of 3 3/4) is due to the tube being too short when I put the race car rack back together. So if anything, the arms on the race car are about right to a touch too long for full turning radius. I checked the race car and with 2 1/8 turns from centered I have full turning radius and the turning stop on the lower control arm is right at the bolt head.
The last three photos give you an idea of what a new Hemi with SRT8 jeep manifolds looks like in an early A. It fits, but is very close on the passenger side, and there is no/little room for exhaust coming off the manifolds.
