And there is another reason why I can’t put the steering box behind the radiator, too far to reach the drag link. Seriously if I put the radiator as far forward as it will fit on top of the frame then it will have to be right at 31″ behind the front of the nose piece. Plenty of room for the steering box and standard pitman arm, but way too far back for even a double-length arm to reach the drag link from behind the radiator.
Something else I found out while I was mocking up and measuring things is I’m going to have to push the box back a smidge from how I initially imagined the layout because the tierod will hit the drag link arm at full droop. As I initially envisioned it the drag link would be parallel to the tierod at ride height and just below it on the steering arm, but in reality there’s less than an inch of clearance at ride height and the axle has to move more than that at full droop. Basically I only have 3″ total travel to work with because of my choice of tire for the Goodguys events will have the bottom of the car dragging if I don’t limit the amount of bump to less than 2″ at the shock absorber because that much travel is also going to compress the tire a bunch.
Anywho, I need to shower and go to bed now, but I thought I should let you guys know what I found out during initial mockup tests.
