Wishbone brackets

[dean211277]

Hi,
Just been out lining up the wishbone mounting brackets on the chassis. However, I have found a problem with them when placed on a flat surface the centre of the holes are about 34mm from the lower edge the book states this should be 30mm.
Effectively this is going to make the wishbones sit 4mm further away from the chassis.
Is this an issue?
Am I going to have to order a full new set?
Cheers Dean
