1978 k5, 3/4 ton caliper swap parts help

[chappys4life]

Working on a 1978 k5 i picked up recently and needs all the basic maintenance done. I was going to replace the calipers, rotors, and rubber lines. It has power disc brakes and a new master cylinder is on the way. I found the 3/4 ton upgrade and it seems worthwhile since i need to change the parts anyway but confused on what I need to buy.
What I found is
1985 Chevrolet C20 (3/4 Ton), 2wd, 5.7 engine
Front Calipers for Heavy Duty brake system, 13" rear drums
These require the 10mm banjo bolt and hose use 1985 C10 with the heavy duty brakes.

So I am looking on napa now and want to verify im getting the right parts
- napa total eclipse 3 5/32" piston calipers CAL SE4674 & CAL SE4673
- napa pads CAL SE4674 (should i use ebc ultimax 2's? cannot find the right part)
- napa brake lines UP 38065 & UP 38066
- 2 banjo bolts for calipers

Does this sound right? I already have the rotors for the stock 78
