Just curious, what type of spindles, ball joints, willwood components and wheels and tires?
I'm building a 69 Dart and considering the same set up you have
Tanks
Wheels and tires specs" Special limited edition American Racing classic Torque Thrust “D”18 Inch Wheels. 6” front 8” rear 5 on 4 3/4 bolt pattern. Front Tires: 235/40 ZR/18. Rear Tires: 245/50/ZR18. Backspace 4-1/2 front, 5-1/2 rear. Hub stubs.
I don't know the spindles and ball joints but I suspect that they are stock. I'm taking the car into the shop next week to have them inspect all the components. I'll be adding QA1 adjustable strut rods. Wilwood brakes system includes 6 piston front, 4 piston rear. 14” Drilled and Slotted Front and Rear Rotors. Wilwood master cylinder.
