New guy needs advice

[Danny Grizzelle]

Hello folks, just brought home a '70 C20 lwb no motor or tranny. Plans are to put the cab and front on a C10 swb frame I got. The frame is bare, it does have a 12 bolt rear end and front end, needs just a little TLC but all in all, it's pretty solid. I'd like to put some drop spindles on and some drop springs, not slammed on the ground but a lower stance. My question is, should I do what I have in mind on the frame first then start the tear down and body work on the C20? Would y'all recommend a order to go in?
Thanks for any help and info.
