Ball joint brakes on combo spindles? Bearings?

[Piledriver]

Looking to press and weld in some new spindle spuds, and would prefer to go a bit beeffier, losing the speedo cable hole would be no issue.

Are there adapter bearings for combo spindles to ball joint drums/rotors/hubs, or link pin only?

I understand the usual setup is for ball joint backing plates and link pin drums etc.
(seems like a weird combo)

A little more research reveals the issue.

Kingpin spindles are metric, as you would expect from a German car.
...and combo spindles are also metric so a metric bearing exists to fit both inner and the kink pin hub.

Ball joint setups went with SAE std automotive bearings, which are inch series, take A1 outer and A15 inners.
Adapters and metric ID/SAE OD bearings are not std bits in any way.

So if using combo spindles, one stuck with a choice of either stock early drums (with ball joint backing plates, genius move) or ridiculously expensive full customs.

I'll look into turning combo spuds down to some std inch sizes that take std bearings and work with ball joint hubs or something standard in any case., would only take a few minutes in a lathe, 99% setup time.

The ball joint spud is only a tiny bit smaller than the combo on the inner, the extra meat is mostly on the outer, 17.46mm vs 25mm combo size.

I'm very interested to see where you go with this.What are you planning to put your combo spuds onto?

A T3, and probably a 914, welded into either the std spindles or welded into a CrMo plate and that welded on via traditional drop spindle method.

I may end up using CrMo Chevy or Mustang2 spuds or such as I'd like to go with some nice, light forged aluminum Wilwood front hubs., which also happen to be reasonably priced and have multiple brake disc/hat options that don't cost $1000 like anything for combo spindles..

The problem with the combo spindles is they don't seem to be standard anything.

The problem with the combo spindles is they don't seem to be standard anything.

But they DO work beautifully well at what Cecil Wright invented and designed them for. Offroad VW front suspension using readily available and work quite well VW drums and backing plate assemblies on a VW beam front end. There are a number of heavy duty offroad disc brake kits available now. When Cecil came up with Combo spindles there were racing disc brake kits available from outfits like AMS to fit Cecil's modified VW linkpin spindles which were already quite expensive for their day. But offroad races were more often won by cars using stock VW front brakes than aftermarket discs back then. The only thing driving racers away from using VW drums was the low quality of drum castings available as replacement stock parts in recent years.
