Thank you, I was familiar with the use of the upper control arm and larger upper ball joint. Just not sure if the 73+ ball joint would work with the stock lower barracuda control arm.
That makes me happy so now I can do my disc conversion with what I have for actually less money than buying a pair of factory 65 lower ball joints. Just hope my outer tie rid ends from the 65 barracuda will work with the 73 lower balljoint/steering arm.
