To be honest there is not alot of variation you can do with this, more personal preference if you have say the rev counter directly in front of you or the speedo. the remaining auxiliary gauges run right to left in whatever sequence you want/fancy.
Recognising the relative minimal variation i decided to use the aluminium instrument surround GBS supply - this gives a nice template to use as a mark up for where the holes get drilled. Out withe masking tape and marker pen it is then!
All marked up, its time to get drilling - remember you are drilling glass fibre - it is not nice to breath in, it can be a skin irritant so "suit and boot" accordingly! (Health and Safety speech over with!)I used a step drill bit to drill through several times to widen the hole and then a barrel sander bit on the drill to remove the remaining bits of glass fibre in each aperture.
end result (apart from alot of glass fibre dust) as follows....
The surround was then polyurethane sealed into position and we now awiat the dials to come through from GBS
