69 Valint disc conversion

You can probably use everything off the Aspen if the parts are in okay shape. Knuckles, rotors, calipers, caliper brackets, etc.

You still need the A3 upper control arms for the swap and you'll have to sort out the master cylinder and stuff like that. You'll also need to sort out the caliper placement if you have an anti-sway bar and you'll need to buy the proper brake hoses.
