No, 3/4 ton parts won't fit.
Check your shop manual for the sizes of the brakes and you can see if they are the same size as another size truck, but probably not.
You can have your old shoes relined, and your wheel cylinders are most likely available at NAPA. Or you can have them stainless steel sleeved and install new kits, don't waste your time having them sleeved with brass.
Jim Carters probably has some parts, like wheel cylinders.
It all depends on what you want to do with your truck and how much money you want to spend on it as to weather disc brakes are a good choice.
I thought they were a good choice for my truck, and am glad I switched, but unless you are a good welder, fabricator, and machinist, or know one and have money, you might not want to tackle a disk conversion on a 1.5 or 2 ton.
