65 Barracuda Disc Brake Conversion Help Needed

I see a number of issues here.

First, you need some kind of upper bumpstop that actually contacts your UCA's. The UCA should not go metal-to-metal on the frame under any circumstances. Next, your wheels need more backspacing. Stock 73+ spindles will not solve this issue, all of the drop spindles out there are based on '73+ disk spindles so the wheels will be in the same place. I checked the wilwood kit you have and it doesn't add any additional track width, but just going from drum to disk spindles adds over 3/8" to the track on each side. You'll have to add at least that much to the backspace to get those wheels to fit. Finally, you lowered the car a bunch. Those tires are 205/70/14's? That's a 25.4" tall tire, which is pretty tall for an early A. It doesn't look like you've got enough clearance when you turn the tires, which means you might need a shorter tire even after you fix the other issues. Early A's are not my specialty so I'm not sure what you can run for tire height without modifications, but it looks like you're pretty darn close to it. The additional backspacing would help.

Finally, drop spindles on a torsion bar front suspension are a waste of money. If you use larger torsion bars you don't need as much available suspension travel, so you can lower the car with the torsion bar adjusters. The larger the torsion bar, the less travel you need, the lower you can go. With the 1.12" torsion bars I run I can set my car as low as it would be with 2" drop spindles using stock spindles. This has the added benefit of less bump steer and a lower roll center compared to what you get with drop spindles, so, better suspension geometry. I see you have Bilstein RCD's and Hellwig sway bars, so, I'm guessing you want the car to handle well? If that's the case, you want larger torsion bars anyway.
