Control Arm question

[Eazyrider111]

Well I have been lurking on her for a few months now and have tried to find as much information as possible but one question still eludes me. I bought a 63 short bed fleet side a few months back and noticed that the passenger side lower control arm had tried to make friends with the curb at some point. So I decided to pick up a 73 Chevy front end and I want to keep my drums but upgrade the control arms. So my question is can I use my stock spindles with the upgraded control arms if I use 63 ball joints?
