ATD spares

Hi guys. I've acquired a rather worn ATD which is complete apart from the cupped washer/ring and 'C' ring. It also needs a new fibre wheel. What I'm not sure about is the spring arms which seem to have slightly enlarged/worn holes. There also seems to be a lot of up and down movement, although this doesn't seem to affect the operation of the bob weights. Should I be concerned? Do I need to replace the spring arms? Are they available?
I'm going to attempt a rebuild of the unit myself so does anyone know where I could acquire the spares I need prior to Priory Magnetos (beezermacc) reopening for business in September? Priory does them at a good price so may wait until then anyway.
Cheers

Those arm things are always sloppy, so yours may be normal.
You could make the horseshoe washer out of a washer.

Thanks TT, the spring arms on the existing ATD (on the bike) are a bit sloppy, but not quite as much as the other unit. I reckon as long as it's functional, it should be ok.
Cheers for the reply.

The C ring etc are available on Ebay (or were, a couple of months ago when I ordered a set) but any mag parts supplier worth his salt should have them.
Try these people-
