front suspension swap?

[drivethechevy]

im looking to swap the front drums on my 69 chevy fleetside for disk brakes without spending a lot of money and one of my dads old mechanic friends told me that the front suspension from 73-late 80's chevy pickups with front disk brakes swaps right in, and he couldnt remeber if i would have to drill any new holes or anything
so what im wondering is if it works? and how exactly i am to go about the swap?

any other cheap ways to get disks on my truck would help me
