This is where people have purchased them in the past: Fast Freddie's Fabrications - Fast Freddie's Lexan Roadster Windshield. I contacted him last year when mine broke and he wasn't selling them any more. But apparently is now willing to consider at least a pre-order. But still not a sure thing it seems. I ended up buying the glass only from Factory Five. But I've already decided if mine breaks again, will go this way: Optic Armor Flat Windows 24X72-3. Same material as I understand. Easy enough to cut out using the old windshield as a pattern. Local buddy did his this way and turned out perfect.
Not personally. But the local buddy I mentioned used that exact product (Optic Armor) and thickness (3/16) on his and it looks great. He said it was an easy install. It's available elsewhere including directly from Optic Armor, and maybe even a generic product would be cheaper, I don't know. But something I can personally say works, and I will immediately go to if I have to. The only difference is that Freddie's kit comes with a new rubber gasket. The Optic Armor or any other acrylic sheet obviously won't. If you're careful, you may be able to re-use what's in the windshield now. Or the gasket material alone is available from Factory Five.
That's exactly what the referenced Optic Armor product is, of which there are other brands as I mentioned. Also what Fast Freddie sells. Good enough for race cars, boats, airplanes, etc. Has some disadvantages, which is why it's never been officially approved for automotive windshields. But strength isn't one of them.
I wonder why Fast Freddie's decided to stop selling them? It would seem he had a pretty good market for them for quite a few years. Perhaps more people were sourcing the material themselves, since it is fairly widely available. The real trick I would think, is the cutting of it.
Ditto. I replaced my damaged Fast Freddie Lexan with 3/16 Margard MR II scratch-resistant Lexan and had the supplying plastic shop use my old Lexan windshield as a template. The one remaining question is whether you need to replace the rubber seal or not to get the Lexan to fit tightly in the frame? I re-used the seal Fast Freddie supplied me previously, so I can't really say if you can re-use the rubber seal that came with the glass windshield.
A problem w/ using silicone is that the WS has a slight curve to it. So in the frame it would be tight against the rear of the frame in the center and tight against the front of the frame at the ends. I have used the professional WS sealer for other uses but this is one I would skip. Either the caulk tube type or semi-solid ribbon type is such a powerful adhesive it would make the lexan close to permanently attached to the frame. There may be something here that would work; McMaster-Carr
While I have not changed a windshield I have seen the results of various sealing methods. The good thing about Lexan is it shouldn't crack but it will pit and may become cloudy.
I'd be cautious when using the adhesive sealants as you may damage the frame if you have to disassemble it. You may want to test a few methods prior to commitment. Not saying "don't" just urging a bit of caution.
One friend vented his frustration with removing the glass on a perimeter bonded assembly with a 3# hammer. Glass everywhere and didn't do the frame any favors but the glass was out.
I intend to switch to Lexan so I am curious as to what others have done. A "U" gasket seems to be a good idea.
As more and more people get put in lock down it's nice to have a forum and projects like this to keep daily life going.
My occolating sander wasn't going to cut the small ajustments I needed on the hood. I got a orbital sander and some 80 and 120 grit paper. I only have a little to take off...
You would think after 15 years on the road I would be done building this cobra. This year I turned 70 and it’s time to mellow out a little. I’ll be replacing the FFR stainless pipes with j-pipes with new cats and Spintech 7000 mufflers. Spintech mufflers have been done before but I’m not sure...
Looking at getting the two piece spindles from f5 should I also lower the rack? I know there are lots of info about bump steer just want mine to go away. This is one of the areas I didn’t research much until I have driven my car for 1000 miles and cringe everyone a bump comes up.
