Lightened Flywheel counterweight - Where from?

[Welsh Dan]

I bought a lightened flywheel, which I ordered with the matching counterweight for it. Unfortunately, the company forgot to charge me for it and forgot to send the counterweight. Although I can order it from them for not a lot, it might take longer than I want. Where can I get the counterweight I need from in the UK? As far as i\'m aware, I just use the auto counterweight, but obviously options other than Mazda are appreciated.

Its an ACT lightened flywheel, going on an FD3S.

Don\'t mess about, get the correct matching one.
 It should be a matched and balanced set.

I would go for the ACT one like mine, the auto one is slightly different
