Hello Dan, nice find!!......one of my alltime favs.!!
Professor motor has repro windshields (look in Vintage/reproduction) that are gorgeous, and they also sell knockoffs (again in Vintage/reproduction), but you will need to buy a set (4).
As far as the chassis/wheels, perhaps you can post a pic. or two.....depending on their state there are a few different methods for re-conditioning, depending on how much work you are wanting to do, and what tools (bead blaster, airbrush etc.) you have available.
I have attached a few shots of a Dino I did several years ago.......it has a PM repro windshield, and has had the chassis restored/wheels painted.
PS I may have a spare knockoff lying around......do you know if yours are the originals??
This is a repro Dino windshield from Prof. Mtr.........likely better than the original
And a couple of chassis shots.......on this chassis, after cleaning, I gave it a quick shot of Tamiya light gun metal spray (it is a lighter shade in person)......if this is acceptable to you it is an easy process. However, if you wish to restore the chassis to "minty" perfection, you will need to lightly bead blast it, and then give it a very very light (and erratic) dust of Candy red paint with an airbrush.
As many Dinos ran with yellow wheels, I used Tamiya Chrome yellow spay after cleaning and priming them......this will stop the magnesium "fuzz" oxidation
