We went with 316 SS allens for the better corrosion resistance. The bolts in the front windshield pretty much reset the angle in the washer by themselves as they bolt down tighter against the solid rubber under the glass. The rears are compressing dense foam that spaces the window up flush with the hatch so they didn't "self correct" if you will. I will fix that. The front windshield frame is perfect for bolting straight into it. I used knurled steel rivnuts. Turned out great!
Daryl I have noticed from time to time that the pics don't show up. Not sure why
