Anybody have the Early Classic Enterprises or McGaughys brake kit

[HeavyHauler]

I am looking to upgrade the brakes on my 1968 Chevy C10 396 shortbed. It came with factory manual drums front and back. I want to upgrade to disc brakes all around and also lower the front and rear of the truck maybe 4 inches in the front and 5 inches in the rear or something close but I dont want any clearance problems with suspension etc.

Does anybody have any experience with Early Classic Enterprise brake kits or the McGaughys brake kits?

I am wanting a kit that if I needed to replace the rotor,caliper,pad,etc that I could go to a local auto parts store and buy them.

I noticed the McGaughys offers a 13 in front and 13 inch rear disc brake kit which sounds awesome but I dont see where they offer a master cylinder and booster that would work with that combo.

Any input is welcome and thanks!
