Front disc after market kit questuon

[Bronk74]

Question: im looking to replace the front disc calipers and pad probably disc also. This kit I ordered from wild horses probly 20 years ago. My question is im looking for replacement parts at NAPA and they ask if it 4wd or 2wd ..
Does it matter?

Pretty sure it is the GM conversion. Pads and calipers would be '74 4WD chevy blazer. Rotor, wheel bearing, grease seal '77 Bronco.
But visually conform the parts.

What I really like about the GM conversion is the huge selection of pads available. I'm not talking about the 5 different choices from the local parts store. I'm talking the 50+ choices since that caliper is so popular is racing and the hot rod world. You can get a lot of brake feel and performance tuning by looking at different pads.
