This is an interesting photo, when did you get your roof fitted ? Mine is in just now because the front cams were squeaking, indicating some sort of movement. The cams sent to replace the ones I have are these ones pictured. Notice there are normally 3 screws holding the cam lock to the roof, but in this design the cam is tightened in a manner that basically sandwiches it against the roof with wavy washer underneath. So even in this thread 3 different cam designs. The skyline videos on fitting still show the drilling of 3 holes and fitting of cams that way.
My converter who is fitting the new cams are concerned about the cam overlap with the bar on the pop top. So are fitting a wider bar to ensure better overlap. Only thing is they only have mild steel instead of stainless so I'll monitor it for any bending!
