For some reason, some pictures come out upside down or sideways. Your first one seems to have been "infected" (lame virus joke!) by this.
Your flares are better than many I've seen and your wheels are an interesting idea. It looks nice. I can see you know your way around a tig welder! That will obviously serve you well in this project!
Turbocharging your motor is an interesting idea too!
The windshield is available from the manufacturer, Pilkington (
https://www.pilkington.com/en/us/automotive/pilkington-classics). They were the OE supplier and they will fit. I've heard of several people who have gotten Chinese knock-offs with unsatisfactory results. Check to see if they have a depot in your area and if so, you can save the shipping costs.
Good luck with your baby and keep us informed of your progress!
