Pablo I don't know of the post but it's real simple I measured up 3/4" with the same spacing and drilled the same size hole, for spacers on the bottom I took a 1" hole saw and drilled 2 pieces out of nylon hope this helps
When I bought my fairing from Wide Open I spoke to the owner and he said he was going to make a kit (spacers, screws, and template for drilling) that was at least a year ago I guess he changed his mind
ps my neighbor across the street bought one and put it on his 07 Pin without lowering the spedo
once again hope this helps
