Fraser They have to be individually made to suit the hood. The door plug-ins are straightforward and rivetted or welded to a 1/4 rod which is bent to the approximate shape of the aperture. You need the hood on first. The drivers 'frame' is split vertically to give a hinged panel to open for signals. When all are ready, take with car to a trimmer who will stitch matching/same material as hood around with plexi-glass for windows. Door units plug-in for and aft and rear side both plug and have a screwed (knurled-knob) to secure. Nick Simpson. Posted by Nickalvis 11/03/2013 22:28:19
