Disk brake conversion

So I'm looking at this new frame that is going under my 70 c10. I realize it has 6 lug drum brakes on the way around. Those gotta go! The rear isn't an issue, I have already converted my TURD 9" to disks and redrilled the axles to 5 on 5, no problems there.


My question is the fronts.

I know I can swap the whole crossmember in from a later truck, which would include the disk brakes and 5 lug. Which is what I may end up doing.

I know most of the vendors sell a swap kit, but I don't have the budget for it.

So I will be hunting the yards for a few parts at a time.

1. Will the 71-72 spindles fit my ball joints?
2. Will the 71-72 ball joints fit my control arms?
3. Will all the steering parts from my drum set up work with the disk set up?
4. Will the 73 and up power steering gear boxes bolt up to my 70 frame?
(My 70 frame is also manual steering)
5. Are the 73 and up front coil springs the same as the 67-72 front coil springs? (either way it's getting a 3/5 or 4/6 drop depending on how it sits)


Thanks guys!
Frank

Re: Disk brake conversion

NWD02, thanks it helped some.

So you used stock 71-72 style parts(calipers,rotors,ball joints,steering) with the drum control arms.

I am assumeing you ordered the 71-72 spindles?


PANELDELAND, Did you study?





Thanks guys you both helped out a great deal.

Re: Disk brake conversion

I found the easiest route was to simply swap the entire front end. So long as you can find a suitable donor with all good components. Keep in mind there definitely IS a difference between power steering box and "armstrong" steering so don't toss your pitman arm, the splines are different size.

You can wish in one hand and crap in the other.
See which one gets filled first.

Re: Disk brake conversion

I ordered McGaughy's Spindles. When you install them you buy them for the truck, I bought them for my 67. The rotors, bearings, seals, calipers, etc. all came from a 71-72. When I ordered McGaughy spindles I spoke to someone in their tech dept. that actually seamed to know what she was talking about. She said use all 67 suspension parts (ball joints, tie-rod ends, etc.), and the brake parts from 71-72.
