	The cab is further insulated at each rear mounting bolt by a hard rubber bumper encased in a metal retainer. The mounting bolt passes through the center of the rubber bumper and retainer, and a heavy cushioning coil spring is placed between the bolt head and cab sill. The lower end of the bolt passes through the top channel of the frame side rail and terminates in a castellated nut, locked with a cotter pin. The position of the rear center cab mounting bolt is reversed from that of the rear bolt in that the cushioning spring is placed below the top channel of the frame side rail and between it and the castellated retaining nut. The other two mounting bolts are not spring-cushioned but fabric rubber insulators are used between the cab sill and frame upper channel at each of these bolt positions. The cushion spring method of mounting is designed to permit the truck frame to weave under certain conditions without placing undue strain on the cab structure. The cushion mounting bolt retaining nuts should only be tightened to a point where it is just possible to insert the cotter pin and no further. Greater tightening would compress the springs to such an extent that flexibility would be destroyed. DOOR GLASS A metal frame is mounted on the door glass with the conventional rubber filler strip; this frame reinforces the glass and at the same time provides freedom from looseness and rattles. Cab Door Glass Replacement 1. Remove door lock handle, window regulator and door lock remote control handles. 2. Remove the door inner panel screws and remove the panel.	3. Remove the screws attaching the regulator board, and tip it away from the door. This disengages the regulator from the cam channel, as shown in Fig. 85. 4. Raise the glass and remove the glass run channel from its retainers on the lock pillar side, then remove the glass. 5. To install the metal channels, place a length of rubber filler strip over the edge of the glass, then tap the channel over the glass and filler strip; trim the filler flush with the channel using a sharp knife or safety razor blade. 6. Install the glass in the door opening, lubricate the cam channel with graphite grease, connect the regulator to the cam channel, as shown in Fig. G5. Reassemble the regulator board, door inner panel, and control handles. When the door glass is removed, a glass run channel may be replaced by removing the garnish molding and then removing the screw which anchors the top of the channel. Door Lock and Glass Regulator Replacement A door lock or window regulator may be easily replaced when the regulator board is removed from the door, as these parts are mounted on the regulator board by screws. WINDSHIELD Windshield Glass Replacement 1. Remove the three regulator arm bracket screws at the windshield frame. 2. Remove the windshield hinge screws, two on each side at top of windshield frame. 3. Remove the three screws from the top and bottom reinforcing plates, then remove the four screws from the center division channel and remove the inner and outer channels with their seals. 4. Remove the screws attaching the top and bottom channels to the frame reinforcement on one side of the center division channel. Then pull the two halves of the windshield apart at the center, as shown in Fig. 86. 5. When replacing a windshield glass, place a strip of Everseal filler channel over the edge of the glass, with the soap-stoned side out. Brush the inside of the windshield channel with light lubricating oil. Push the glass with the channel tiller into the windshield channel by hand. NOTE-The oil acts on the channel filler, causing it to swell, thereby making a perfect watertight seal. 6. Assemble the windshield halves and install the screws in the center reinforcement.
