Glazing covers all the glass and transparent components on the Midget, the windscreen, quarter light assemblies, and drop glass (door windows). Each changed during production, and the correct specification is determined by the chassis number.
Windscreen
The windscreen is a laminated glass panel seated in a rubber glazing seal within the windscreen frame. Laminated glass is the only type now available, it will crack under heavy impact but will not shatter, holding its shape within the plastic interlayer. Clear and tinted options are available. The windscreen frame was finished in satin silver throughout most of production, a brief change to black epoxy coating for approximately 3,000 cars in 1970 was quickly reversed, and satin silver frames were then fitted through to the end of production.
The glazing seal between the glass and the frame, and the seal between the frame and the body, should both be renewed whenever the windscreen is removed, fitting with soapy water as a lubricant ensures the seal seats correctly without tearing.
Quarter Light Assemblies
Three quarter light types were fitted across production, each interchangeable as complete assemblies only. The earliest type (to GAN4-64474 / HAN9-75702) has a chrome frame with a hooked locking handle.
The second type (GAN4-64475 to GAN5-121649 / HAN9-75703 onward through HAN10 and AAN10) has a chrome frame with a straight locking handle. The third type (GAN5-121650 onward through GAN6) has a stainless steel frame with a straight locking handle. The quarter light pivots on a hinge pin that can seize over time, penetrating oil applied over several days often frees a seized pivot without the need to remove the assembly. Quarter light seals, pivot pins, and locking handles are available individually.
Drop Glass
Drop glass (door window glass) is specific to left and right sides. The glass slides within channel felts that compress over time, causing rattling, slow winding, and water ingress past the glass into the door interior. Inner and outer weather strips, channel felts, rear channels, and the lower channel should ideally be renewed as a complete set per door for effective sealing, renewing only one seal while leaving the others aged and compressed rarely achieves a satisfactory result.
Windscreen Frame Pillar Seals
The pillar seals sit between the windscreen frame uprights and the body, sealing the joint against wind and water. These are handed left and right and should be renewed if they have hardened, cracked, or compressed to the point where they no longer form an effective seal. Wind noise at speed and water dripping down the inside of the A-post are the typical symptoms of failed pillar seals.
