Holden 6 Cyl VC HEI modded to fit Bedford. You can see the four posts that I have bent to 90 degrees by this point, one of the springs still attached, they were later bent 180 degrees and the plate they are attached to flipped upside down on the shaft. Image and info by fjwb. Click to Enlargen.

Bedford Distributor Modification:

Fjwb has generously provided info on how he adapted the HEI Distributor from a 6 Cyl VH Commodore to fit the 214 cu in Engine in a K Series Bedford.

Reverse Direction:

The VH  Distributor rotates clockwise and had to be modded to operate in the anti-clockwise direction. The plug leads had to be positioned appropriately and the balance weights modded.

Method:

Well it's done and working. Took about an hour of tinkering. Essentially pull it all apart, had to grind 3 welds off to reverse the mounting plate on the distributor shaft and weight pivots. But it's back together and working as it needs to.
The motor runs so much smoother just from the HEI conversion.

It's HEI. It has no points. It was a brand new VC commodore spec dizzy from RAE for 173-202. I pulled the base plate off the shaft and flipped it over, I removed the two weight pivot posts from the base plate and flipped them. I bent the other four metal tangs (spring mount and weight limiter) 180 degrees to face the other way, welded it back together and reassembled. Re distributor curve, I don't know that it's the correct curve. I wouldn't go bolting into a race motor, but it will now only fit the 214 long stroke Bedford truck motor, it's running fine, And the advance is working, I may (probably won't bother) getting it adjusted. The fact of the matter is it's running 100 times better than with the old worn out points dizzy, that is totally obsolete, new service parts like rotor and cap do not exist. It's doing the job just fine as is.

further to the other comments,
the mounting pad where the dizzy sits on the block of the red/blue/black 6 cylinder needs to be machined smooth with the shaft, 4 ridges that extend from the shaft to the body of the distributor need to be filed smooth so the dizzy can sit further into the block of the Bedford. The hardened steel gear from the Bedford needs to be drilled with a 5mm drill to fit into the existing hole of the new distributor. This was probably the hardest part, although I found a masonry bit with some sharpened edges will go through hardened steel like butter. The shaft of the distributor needs to be shortened about 10mm so that the gear engages the oil pump.
There may be an easier option than this, but having an old red dizzy laying around I knew that at least making it fit was possible, making the advance work the correct way could come later. I have disabled the vacuum advance at this stage as that was still working the wrong way, it could be reversed though.

Drilling:

5mm drill through roll pin hole on the Bedford gear so it will then fit the new dizzy. This was probably the hardest part and even a cobalt drill didn't scratch the old gear. I done a bit of googling and believe it or not a masonry bit was the way to go. Sharpen the edges of the masonry drill and it went through the hardened steel like butter.

Ridges:

The ridges are casting marks extending past the upper section of the machined shaft to under the body of the distributor, i.e. Where the weights are house.
