Oops,
I have just found that the 626 in question is a GD not a GE
Oh well back to the wreckers next week.
The only thing on the thread was that it is posted in the MX6.com 1st gen section. On the bright side the GD rotors are only 10mm smaller than the BA V6 rotors.
If I do need GD rotors they should be much cheaper than the BA V6 ones, Greg?
