360 starter mount compatibility woes

My apologies, I missed that part about the chassis.

What's the chassis application, and how much space-time interference are we talking about? I realize it probably won't help, but some of these guys are versed in a lot more than Mopar
1960 Ford Falcon with 1967 Chevy G10 Van I beam axle with parallel leaf springs. I found an old gasser in a barn and it one time had the complete van side steering setup with the column between legs to steering box under seat and the drag link running forward to the drivers tire.

But now it's getting a side steering drag link to the passenger tire.

I have 2 falcon boxes to play with, even got ready to reverse one, but then picked up a Vega box which is both more compact and bigger depending on which dimension you view.

The steering arms are rear steer (they point rearwards from the axle and are connected with a solid tie rod). The passenger tie rod end has an extra hole to accept a drag link from the steering box.

If i move the steering box (either one) just a bit forward to get a head of the starter, then the forward pointing pitman arm is far too long to reach the tie rod. I'd need like a 2 inch long pitman.

My most recent attempt was either box moved forward, sitting JUST behind the axle, with the pitman moved 180 degrees to point back to the steering arms-tie rod. To make this work, i'd need a steering reverser from Coleman, as well as making sure the tie rod doesn't travel up into the pitman on bumps.
