I am looking for a set of TCA for my MKII Series 1 as part of the spares pack required for the endurance rally I am in..... which leaves in less than 9 days!
They don't need to be mint cond, just usable if I bend the others!
Newford Parts Centre usually have them in stock.
If you weren't in such a hurry, you could have ordered them from the Camelot/Transteering factory in Australia/Taiwan (part number BJ142, see page 22 on http://www.georgestock.co.nz/catalogue/CAMELOT/CAMELOT.htm ).
