Lil Giants: this looks like the right setup for correct Ackerman geometry to me. There are 2 challenges here as you mentioned: having the rear steering arm clear the driveshaft and the other is setting up a steering linkage from the original location of the servo (in front of the axle.)
Here a YouTube example of another ingenious solution: using steering arm extenders for a steering linkage in front of the axles. This moves the lever arm outward past the kingpins and into the inside of the wheels for correct geometry. When I look at my truck models the clearance inside the wheels looks very, very tight to do such a setup.

I use the tlt's in two of my GL's.
Try doing it with the tie rod behind once and measure the difference in radius of the turn. It's a hassle to raise the tie rod with spacers to clear the bell on the diff & make a wishbone to pivot off the top of the steering knuckle for the steering servo to remain in the stock position. |
