I broke a 1/4 gl*** in a Ford Probe about 35+ years ago and it cost me over $1,100 then. I put my hand thru it when I was installing it didn’t have the line up pin properly located and when slapped with the palm of my hand to set it, it shattered into what looked like salt rocks
Sounds like it was tempered gl***. I slung a rock with a weedeater into the side window on a 89 or 90 model Ford Ranger once. I found gl*** EVERYWHERE in that truck.
Tempered gl*** was used in the corner windows of the Chevy AD pickups in the '50s. So, it is traditional.
Trevor and Saul showed up this morning and we did some wiring, and started ****oning up some stuff under the dash so I could get the firewall pad in and get the Vintage Air evaporator hung under the dash permanently. We got the windshield wipers working and had to knock off so Trevor could go get some POS plastic off topic junk. I let him borrow my trailer but he earned rights to the trailer years ago by helping me rebuild it. The wiper motor is a Newport Engineering unit with intermittent wiping and the "park" feature. Easy and neat, clean install on that motor. Works excellent! https://youtube.com/shorts/Oz8yXzwoS1k?si=c42x0vfmOTuI_JjT
