Frame sections

[67ChevyPickupMan]

I have 1968 Chevy C10 long bed, 2wd coil spring, frame rails in my back yard and I was wondering if anyone could tell me what sections I should save and how should I cut them out(Length, Tools). It does have a rust hole by the driveshaft hanger cross member and the passenger side front rail is bent a little from a crash it took part in. Besides that the rest of the rails are in good condition, just need to be sand blasted and painted.

Thanks Jack
