I have a D60 single rear wheel axle I am wanting to put in the rear of my 75 Supercab. I will then need to go to 8 lugs on the 2 wheel drive frontend.

Will a single piston caliper 250 hub and rotor fit on my existing 150 spindle?
I did a parts search on some online autoparts store and the single piston caliper brake setup for a 3/4 ton 250 lists the same inner and outer bearings, caliper, and even spindle nut that my current 150 stuff has?

I hope it works! Anyone done this? I know the dual piston stuff does not.

 

no they won't fit. but just swap the ibeams over then it becomes a direct bolt on. you will also need the master cylinder and booster along with prop valve.

 

I may be a little lost here, but the parts list says it uses the same king pins, calipers, bearings etc... Why would I have to swap I beams? This is not the dual caliper 250 stuff. Supposedly I have the large kingpin beams allready??

 

what parts list? the bearings are not the same.

 

IMO I'd swap to F350 calipers like in the tech article of this website. Provided it allows the rotor of the same be swapped. I believe what 390 gashog is saying is, the steering knuckles the calipers bolt to, are different between 150's and 250's, and since you are stating using the original single piston calipers, you want to know the dimensions of the rotor. Which I believe is a larger diameter which won't allow you to use the same caliper. spindle size, bearing size, or whatever...if the diameter is different, it won't work. Hope I've added to the confusion enough.
