Thank you all for the support on these. I think I finally have the design fairly locked down, little thicker, a little shorter overall and 4 magnets. Going to stabilize the price at $20 shipped in the lower 48.
Made a few of these for myself, wanted to gauge interest- $15 shipped to the lower 48. $10 to the first person if you will give me some feedback. I have 3 in stock.
I am running a 74' 40 and it fits over the blank space nicely and stays secure. 2 neodymium magnets hold it on from opposing corners.
Parting out the top half of a pair of pre-75 doors. I have both the driver and passenger side glass (big window)- no chips, light scratches in the usual spots, with the attached metal mounts.
Etching on glass says "Temperlite AS2 ASAHI M215"
I have closer pictures, pm me if needed- $40 each...
