brake drums, are they the same on all models? where to buy?

as above, are they all the same? and is there a reasonable priced source to buy from, or is it a case of getting second hand ones?

Why do you need them?

I don't need them jusy yet, but a fabricator guy I know said he'll have a look at the possibities of adding a wheel locator flange to one, but if it works, the standard wheel wouldn't fit back on, so I'm just testing the water to see if its worth bothering
(Reason being ive got some 4x108 wheels I'd like to be able to use, and I can't see another way to do it)

Wondered why myself, that explains it

There is a much simplier way called "offset wheel studs" which will give you 108mm pcd they come in a range of fittings and lengths and if you want a locating centre a thin spacer type plate with the centre spigot on will do that and niether option requires permanant modification.

It was my intention to use wobble bolts, but they just aren't safe without a central spigot in my eyes.
A spacer with a spigot would have the same issue, as there is no initial spigot to centre on. Unless the spacer had a spigot going into the drum and into the wheel

Locate it on the studs like the standard wheel if you use offset studs they are pressed into the mounting flange and have a shape to them that I cannot remember the name of right this moment to stop them turning when you do the nut up.

Do you use these? I can't quite get my head around how they would work

Simply they are dangerous without a fixed centre mounting spigot. I know folk will disagree, but they're not the best idea.
