I think that's the only big body drop spindles you're going to find,I was just looking at my arcives,Oct 04 Popular Hot Rodding,78 Malibu,Jason Herrera,says dropped B-body spindles,B-body brakes with 12" rotors,I never have investigated it as I havn't had the funds to invest in that sort of system as of yet but it you check out Global Wests website they will or at least did tell all about the B-body spindle conversion and using the Camaro 1LE 12" brake rotors for the 5 X 4 3/4" bolt pattern as the later big cars have the 5 X 5" wheel bolt pattern,of course they don't say anything about using a dropped spindle other than dropped spindles don't help the handeling situation which is what they're all about,I would deffinatly do some studying and make a few phone calls before I shelled out $400 plus on those spindles though! Good luck on the hunt! KillerDave
