Drum brake drop spindles - Disk conversion?

One of my 68 c10's has Drum brakes and 2" drop spindles.
Is there a way to convert to 6 lug disk brakes using the drum spindles?

Re: Drum brake drop spindles - Disk conversion?

No one makes a drum drop spindle to my knowledge. Pics of this setup please.

I think Speedway motors has a setup that uses the drum spindles but smaller passenger car brakes and the 4 3/4" bolt pattern.

The way to do this correctly is to replace the spindles and use truck brake parts. And yes, you can keep the 6 lug pattern if you want. I just converted my truck to 5 because the wheel choices are so much better. For me it was worth the trouble and expense.

Early Classic Enterprises has 6 lug disc conversion kits as well as 5. Good company to work with that makes good parts.

Yeah, I guess, I could post a pic. Somebody does (or did) make them.

I would like to find a way to use them, as I already own them.

Beg to differ, amigo.
People have been customizing these trucks since 1967, You really think, nobody ever made drop spindles for drum brakes?
Well, somebody did.
I'll post some pics.

Still wondering if I can use them for something.

Re: Drum brake drop spindles - Disk conversion?

I've been around these trucks a long time and haven't seen one. Please post pics. I've seen some home-built spindles (cut and welded) but no production ones.

Re: Drum brake drop spindles - Disk conversion?

actually scarebird makes a kit that adapts the 88 up light duty 3/4 ton 6 lug rotors and calipers to the stock drum spindle. the kit sells for around $200 not including the rotors, calipers and hoses. I looked into it before I bought cpp drop spindles and 6 lug rotors

Re: Drum brake drop spindles - Disk conversion?

Do you have a clearer closeup shot? I've seen some before, but they were all cut and welded and I can't see any details in that one.

these were the best pics I could get. I didn't feel like laying in the mud. I assure you, these are manufactured, not hacked and welded.
Maybe, they were made in the 70's or 80's?, I don't know.

But THEY DO EXIST

Maybe, since they're [apparently] the only pair in existence, I'll donate them to the Smithsonian.

Re: Drum brake drop spindles - Disk conversion?

Interesting. We do need a clear picture. If they're not welded but cast one piece some small shop must have made a small amount. No one has ever made reference to those that I'm aware of. And they don't exist in any one's current production or availability. You may have one of a very, very few ever made.
As far as your 6 lug desire, you should be able to bolt up a bracket kit that fits drum spindles, or buy the readily available drop spindles and use the special made 6 lug rotors instead of the 5 lug version.
If you can post a clear picture of those. The drop is the distance from where the upper anchor bolt should be to where it's located now, looks like it might be closer to 3"?
