[Clatterville trolley]

I just purchased a 1967 C20 and am thinking of building it into a driver. I would like to switch it to disc brake front spindles and wondered if they will interchange with a 71 C20 and up disc brake spindle like the C10's interchange?
Also, what else would I need to do / use to make that work on my 67? Such as do I need different steering linkage / linkage parts, ball joints, etc.?

Thanks, Jay
