Thanks for the input. I've emailed them with regards to shipping costs as it looks like it'll end up being half the price in $'s than in £'s ($61.00 or £62.00, which is approx $124.00) - Yeah I know...

Question though, I've replaced the clutch bell when replacing the gears, the model number is G84307-04 - it doesn't quote that it's made from steel but it looks exactly the same but with T15-T18 instead of the 15-18 combo.
Would I still need to buy your option?

Cheers
