As previously stated, £350 for the full kit. This includes a % towards the forum (about £10 as agreed with Mr P), I can get the bits - You order today, you get in 3 days.
I think the difference in costs between the Seat arms and the TT arms is the extra machining required to take the TT ball joint.
I would like to do a GB for the forum, for forum users. i have a good 'in' to the whole VW Trade system, and can do any parts. Not looking to make a living, but it may just pay for the forum.
