Rear control arm assembly question

[ClassicGuy]

I have a 70 C10 short bed with a leaf spring rear suspension. I want to change it to a coil spring rear end. Anyway I was wondering if the rear control arm assembly and everything else that goes with it as far as whole spring rear suspension is the same from a long bed to a short bed. Meaning if I found a long bed at the junk yard with a rear spring suspension, can I take it off and put it on my short bed?

Thank you for any information
