My awesome suspension

There’s no way I would pay for a disk conversion that reuses the 9” drum spindle. Not a chance.

Undersized wheel bearings, undersized lower ball joint to spindle bolts, both of which had plenty of failures. Nope.

Especially not when you can get a 73+ mopar disk conversion with the spindles for less than the wilwood kit. Can’t run the stock drum wheels with the wilwood kit anyway.
Who sells the kit you're referring too? Would it fit a 67 Barracuda?
