Hey!
@rsquire Sorry for the delay in getting these additional pictures, I kinda ran with them off for longer than expected due to getting sick two weeks. Sorry for the dark pictures, but that's what you get for living this far north in January.
Side view to show the about height
Mounting plate on the roof of the car. I have left these mounted since I bought the rack, was a bit fiddly to get them on first time. Comes with a rubber seal to go into the screw hole to keep water/ice/dirt from getting in. I thought that I would have lost them before the end of summer but they have been in for probably 100000km and never even been the slightest bit close to getting lost.
Screw in mount, its a thumb screw, but at -20 it gets very cold very fast and there is not enough clearance to get at it to screw it in with skii gloves on, it is possible with a pair of pliers and some patience, taking them off is a 5 minute job(all four corners combined that is) even in the winter.
