Hi all, does anybody know what size the screws/bolts are that fix the sliding gear to the sunroof metal frame on the underside through the 6 holes (3 each side). I’ve got a replacement glass/frame in great condition as my original has rusted in the front corners. I can’t remove the rear screws/bolts to get the dimensions and would rather wait for the auto glass chap to remove/refit (front screws/bolts look like blobs of rust!). Will be buying stainless versions but just need to know what size??? Any help would be appreciated! Thanks very much in advance
