Mate i know your delema, but here's the easiest way and the cheapest.

1. We left the complete diff in place, including axels.
2. We went to the wreckers and bought a set of EA Falcon rear disc brakes for $60 including backing plate.
3. We redrilled 2 new holes in the backing plate to line up with the standard studs.
4. Dragged out the plasma cutter OOOHHH YEEEEAH cut the center out of 2 of the drum brake covers / cleaned up / painted.
5. Bolted everything up.
6. DONE & DUSTED.

All up the cost was about $60 for the brakes, the drum covers were free, 4hrs with my mechanic @ $60 per hr. Having said all that, once we had everything fitting nice i went out and bought a nice set of shiny new brakes, which will go on when we put the van back together. In my opinion that was the cheapest disc brake conversion i have seen.
If you are not in a wheelchair like me you should have no trouble if you go this path.

Hope this helps.

I think I've asked this before - but I will ask again, did you end up with ford stud patterns on the rear - if so the diff must have been out of a big ford and not a Bed Ford

Yep you did ask b4, thats cool warren. To my knowledge someone has redrilled the hub, you can see where they welded up the holes, when they did that, they ended up with a HQ pattern, when we went to disc brakes, we bought a blank rotor/disc and drilled it out to HQ to match the front. As for the front, we just bought a HQ disc brake kit that bolted up. As for what the original diff and stud pattern was, i still dont know unfortunately, all i know is that when i bought the van it was fitted with 14x7 HQ jellybeans. Now that i have gone to disc brakes all round, i now have to go to a 15" wheel to fit over the callipers. The fronts discs cost me about $1,200 approx and the back cost me $60. Crazy, i could of sworn the back was going to be a nightmare and cost the world, but no the front was the headache and the costly part, you just never know.

To get this thread back on track, exbedford is 100% correct with his part numbers.
I have been doing alot of research into bearings of late, and will be writing up a definitive thread on such details, however as was stated:
The standard bedford bearing for the smaller stub axle is:
M12649/10
Bore:   21.430/0.8437
O.D:    50.005/1.9687
Width: 17.526/0.6900

The Ford bearing is:
LM12749/10
Bore:   21.987/0.8656
O.D:    45.237/1.7810
Width: 15.494/0.6100

The Pontiac? bearing I can only find details of in the SKF catalog:
SKF LM12748/10
Bore:   21.430/0.8437
O.D:    45.237/1.7810
Width: 15.494/0.6100

The ford bearing is usable, however is not a correct fit, as it it quite considerably larger than it should be.

Good work to exbedford for pointing this out.
