Anyone else having problems as I must have sold over 120 sets now and never heard this ?

Dave your problem was when we changed from an imperial bolt to a metric one (the metric one wouldnt go throught the spacers fully so it was nothing to do with the actual spacing width)

Is it at all feasible for someone to have overtighten the previous bolt and clamped up the crossmember slightly ?

Im baffled ??

If it is 2mm Dene we can machine 1mm off each side for you thats not a problem.

The cosworth Ford spacers are CNC made in batches of 500, and just come out of the same parts location as all the others have done previously.

Something has to be odd somewhere
