It sounds like your glass may have been cut to be butted in the center eliminating the division bar, with the center filled with a bead of clear silicone. If you can get a good pattern of the original cutting a !/4" or so off the end is possible. Also you could ask the shop to seam (bevel) the edges if they aren't already. If the edge isn't seamed it will hang up on the rubber during the rope-in, making the job harder. Try not to get too much lube in the moulding groove and use lots of masking tape over the moulding to help hold it in place. the tape can be pulled out after everythings together. Murphys OIl Soap is a old trick for lubing to rubber lip that pulls over the pinchweld. It cleans up easy and won't dry out too fast like silicone spray. Hope this helps. John
