The man wants MORE caster. How about this idea?

This brings up a question that I have about the 73+ spindles. On my '68 FS FB, I installed 73+ UCA and spindles. Naturally they are wider. But I had sway bar and tire clearance issues with the calipers mounted forward as is stock, so I swapped side to side so the calipers were towards the rear. Worked well but not happy with brake line routing. During restoration, I purchased the Helwig bent sway bar which allowed clearance for the 11.75" rotors and calipers. OK, Happy with that. But the tires moved forward by about 1/4" or a little more. I was running 235-60x15's BFG's before with good clearance. Tight, but no touching. After swapping the spindles back to stock, the tires interfered with the front lower edge of the finder. To get clearance I had to go down 2 sized to 215-60x15's. Not desirable! The wheels are Weld 96-57208 ProStar's with 4.5" Rear Spacing. I am not sure if there are other back spacing options that will give more clearance. Does anyone know if the spindle centerline is offset so that swapping spindles side to side changes effective wheelbase by maybe 1/4" or more?
The 235-60x15 Front photo is of the tires/wheels I ran for 10 years with no issues with the caliper mounted to the rear. With the caliper mounted to the front (see photo), even the 225-60x15's touched the fender (the tire is mounted on a checking rim that is adjustable). So I went with 215-60x15's to clear the fender (but no photo).
Thoughts?

I ran rear mounted Pin Calipers on 11.75" rotors with stock LBP UCA from 1993 to 2011. Lots of only car daily driver miles, road course and autocross track time... no issues. You just run a banjo ended brake line. I made up braided steel ones. Dr Diff sells them now.

Personal preference, I would have left yours in the rear and got good brake hoses. Especially since you are running the 67-72 wide sway bar setup.

When I put the Hotchkis TVS upper control arms on, the caliper hit the upper control arm when fully turned. So I had to mount them up front just like you did.

After the spindle swap, the tire clearance did not change. And I'm running real close tire clearance. Of course I changed to adjustable strut rods and UCA's at that same time.

Was not my preference to run them in the front since I want to run brake cooling ducts up there. But I haven't done that yet and will probably upgrade my calipers at the same time.

Most people don't use the Pin Type, so I think it's an under the radar situation. But nonetheless, it can happen. And UCA manufactures should give the customer a heads up.

@HemiDenny Have you checked this not common scenario out with your UCA's ?
