Posted by Instructions are quite clear. My composites were not pre-drilled.
The right-hand side spat fitted very nicely. The left-hand moulding appears to be different. The shorter ‘neck’ and support panel has less depth. A lot of fettling is required to get a good fit. Needed to take 5 mm off the neck of LH main wheel spat. Need to be very careful not to cross-thread the bolts in the rivnuts. They would be a real pain to replace! Used a homemade hole finder to align the front spat fixing holes and tow clamp holes. Used mobile phone on the floor to see into the spat, this was an enormous help.
