    I need some help with a rear disc conv for my truck.I have a 80ish K30 dually with 14 bolt FF. I work at a auto parts/ salvage yard co. so I can get rotors and calipers but need help with mounting. TSM says their set-up will not work with dually. Any help? Thanks

    Ack. It's kinda rough, as there aren't many, if any, kits for the dually.

    The likely rotors will be a later-model truck. I got rotors for a 2003 DRW 3500 Express van, IIRC.

    I'm using Caddy calipers, but you could just as easily use the typical K20 fronts.

    Mounting, you're on your own. I think the rotors I used are slightly larger diameter than the typical K20 rotors, so I had some wheel fitment issues even on my 16"s (damn deep dually rims :o )

    I ended up brutally hacking a set of DIY4X's bolt-on disc brackets (sorry Kert!) and welding them onto a set of flanges which I'd moved to convert my SRW axle to DRW. That's my fault 'cuz I didn't start with a dually set up, and I wanted to keep the axle width down so I didn't hafta add bubble fenders.

    Oh, that's another thing ... you'll need to determine the bracket mounting location yourself.

    Anyway, I would get a set of weld-on brackets, rather than the bolt-ons ... somebody makes them, I believe ... but be wary of the rotor diameter.

    All that said, I'd not go back ... my truck stops very well, considering it's a C30 crewcab, and I never have to deal with those gigantic drums again =))

    PM Rooferbret. IIRC, he had a disk brake set up on his dually.

    can and chassis 14FF would've done that, and probably accepted a standard 14FF disc swap no problem.

    Umm, a C&C is the same as an SRW, except with the dually hubs, and the flange moved in. Yes, mine would prolly have worked out, except the rotors are still an issue, unless you have like 6" spaces.
