If it were me I'd box up that SSBC stuff and send it back, and convert it over to factory Mopar stuff, using either 73 A body disc spindles (or the later F M J spindles) 11 3/4" rotors, calipers and caliper adapters from a Cordoba, a manual disc master from a 73 A body disc brake car and either an adjustable prop valve or a 73 A body disc brake prop valve. That swap has been done hundreds of times by lots of people - the 'hard' part is scrounging up the parts, and they really aren't that hard to find if you look. Only point in buying a kit like SSBC's is the 'convenience' of it being all in one box, but if it works like trash, why bother? My
