I'm trying to figure out what i need. The drivers window (electric) on my '69 442 is missing what i think is the "glass bearing fastener and cap" as described in the '69 service manual, page 6-65 figure 6-82 parts# 8 and 9....i think. It goes through the window and attaches to the rear slide channel to assure the window opens and closes straight. The window flops some and does not close straight. Any guidance, thoughts help is DEEPLY appreciated! first picture shows the relative location of the missing piece; second shows the hole in the bottom of the window where the missing piece goes; 3rd. pic shows the picture in the service manual that depicts the fasteners, mounting bolts, etc. Hobs
