It will work !!
I cut off the front of the frame from a 1976 C-10 with a gas powered rotary disc track saw.
It gave me a crossmember with power steering and disc brakes. I did purchase a new master cylinder, proportioning valve and power brake booster and the mounting bracket. Put in new bushings and ball joints. Also eliminated the hydraulic clutch with a 200-4R.
It is almost a bolt in, two bolts fit, two holes to drill in frame. And remount top of shocks and brake hoses in new holes.
Mine is a 62 so unfortunately I loose the torsion bars for coil springs. But it is a upgrade retrofit for junkyard prices !
Go for it !!
