the front end is ford, because the transverse leaf configuration in my opinion looks better than the gm parallel leaf. the spindles are 37-41 style and will accept any brakes from 37 to 48 i believe. if you have a 36 ford axle, then yes the 37 drums will fit, or you could go lincoln backing plates and run some pretty buick finned drums. as for the disk kit, its from speedway and comes with gm metric rotors,calipers, and caliper brckets for 37-48 spindles. the key is the machined adapter that slips over the spindle to form the surface the inner wheel bearing rides on. seems like a good kit, just not all that cool looking.
i dont love it but it was free and should stop real nice. i may try and do something like so-cal speed does to hide the setup.
