CPP drop spindles and the Brake Bracket Kit

[brandnew72]

1972 C10 LWB
Factory front discs with factory sized rotors (slotted/drilled)

Ordered new 2.5" drop spindles from CPP and all the phone calls led me to believe you HAVE to have the bracket kit. So I ordered a kit because I couldn't find any info stating otherwise. Spindles won't be here until this week unfortunately, but the bracket kit arrived today.

The bracket kit is freaking huge, lol. I'm fairly certain it's for larger than factory rotors or upgraded brake kits. But, I also figured if I got it all apart and didn't have the bracket and needed it, she'd be sitting on blocks for a week or more.

Has anyone needed the brake bracket for factory brakes with CPP 2.5" drop spindles on a 72 C10?
