SSS axle shims

[Simion Wabs]

Any idea where I can get these from without paying more for postage than the item value?
Or any alternative AE/Losi/Durango alternative?

1/4" ID x 5/16" OD x 0.004" Width

Part number U4112?

Thanks

Si

I use the AE versions (part no : as4554), only because I already have some in my box.

7mm ID shims work well and you get a few different thicknesses in the packet, a few companies sell them but I ordered the 3racing ones on ebay from HK, think it was about £4 all in.
