    im game :lol:.

    legitimately gonna look into this, I always had the 14FF on the books eventually but given current circumstances now might be a good time to go for it. Any idea what it would run to have the holes welded up? Would you want it treated after that or plenty strong as is?

    btw kyle in reading the 14 bolt bible on pirate, there are the two different styles with the later design having the slide off drum. would this design difference affect this process at all and make one more desirable than the other, or would either work fine? reason I ask is there are a few parts, including a 97 3/4 burb 14 bolt, that im looking at in sac that i could probably pick up for next to nothing.

    i can probably pick this one up for basically nothing with the other stuff, and in searching craigslist everyday for the past month for various things im looking for, 14 bolts have gone up a bit, more like $150-300 easy most of the time it seems with the occasional cheapo here and there

    Here is the third method for converting the 14FF to 6 lug.

    My hubs accept a 6-5.5 wheel AND use the run of the mill 14FF disk brake conversions you see everywhere.

    How this works is as follows:

    1. Hub snouts are turned down.
    2. 2 of the original 8 lug holes are plugged.
    3. 6-5.5 pattern is machined in.
    4. The remaining 6 of the 8 original holes are tapped for a 3/4 - 10 bolt.

    I would first press in the studs, and then bolt the 8 lug rotor to the back of the hub.

    Of course, I need the turned down SHCSs.

    That is how mine is going to work.

    interesting approach as well, and thats what ram grinding did for you? would the method kyle described not work with the traditional disc brake conversion kits? if/when i do this, i will be looking to go 5.13/eaton/6 lug/disc (preferrably big discs to match big brakes in the front, if anyone happens to know how big the available kits allow you to go?)

    I finally just went with the 14sf. Too much trouble trying to track down hubs... so now my 14ff is collecting dust until I find a new project for it lol...

    14SF seems to be holding up well though...

    It looks like Bryan's version will use the 6 threaded holes for the bolts to hold a standard 8 lug 10 bolt disc on the back just as pressing the studs with the disc under the head works like normal.

    Not sure the plan with the soon to be protruding 6 on 5.5 studs though.

    Standard Chevy 3/4 ton '73 4x4 rotors are the standard for 14FF discs.

    kyle, so whats brake setup with the method you described? sorry im still trying to get a good visual on the whole assembly, never actually seen the 14 hub/axle in person without wheels and tires on it. 6 lug rotors i assume?

    The standard disc brake swap on the older style press on drums just requires replacing the drum backing plate with a caliper mounting bracket (and a 73 K20 caliper) and replacing the drum with a 73 K20 (8 lug) rotor that then presses onto the back side of the hub via the wheel mounting studs.

    My try at it, without the bosses on the back, and a slip on rotor. I think it was worth it for the little extra time making a caliper bracket. No need to ever have to pull the shafts or hubs off unless the wheel bearings or carrier need service. 30000 miles in 2 years and it has held up to all i can throw at it.

    i like the way that looks, what size rotors and what calipers are you using? hows the braking power?

    Stock OBS front rotors and calipers. Braking is great, the prop valve really made the truck stop on a dime.

    did you make your own caliper bracket to use that brake setup?

    Yeah the calipers had to be offset more to the outside, as the OBS rotors are shallower. Figured it was easier to make caliper brackets now than tearing hubs apart later to change rotors.

    i was given a d60 rear i wanted to know if swaping it over to 6 lug would be the same amount of work

    More than likely, because 60 hubs and 14b hubs are interchangeable.
