62 C10 suburban/ 72 suspension Advice needed

[68Classic]

Hey all,

I'm in the inception of starting my suspension and chassis mods & need some advice based on everyone's experience. I've started working on my 62 suburban and will be changing to 5 lug. I'll also be putting it on bags and plan to go as low as I can (within reason $$$) I have out of a 72 C10 the entire front cross member and suspension & 12 bolt rear. My question is. Is it more cost effective to rebuild & restore the old 72 front cross member and suspension which will include airbags (it needs every bushing and ball joint replaced and bag cups fab'd into the control arms, cleaning and paint), or purchase new aftermarket upper and lowers, ready to go? I'm not sure if I'll need to move the control arms up and forward to accommodate the wheels and tires. Hoping to run 20's if I can afford it.

thanks for your insight, I'm excited to get this underway.
