He's right...in fact
there's been a small (very small) cottage industry making "regular" Racers look like Abarth's.
You have the Racer quilted dash and Racer side cards, but didn't see the Racer console. Looks like you have a ton of body work to do, having done the same on mine I'd say you have several hundred hours of work to do.
Good luck with the car! It's worth saving and I'm very glad you plan on doing so. It will be a very unique car at car shows when finished, if you plan on going that route.
I'd gently suggest you NOT sell your extra parts immediately, just until you know for sure what you are going to need. Since you are in Hawaii it might be very difficult for you to get spares in the future. Admittedly I have no idea what the real parts availability is where you live, and am making a SWAG.
But good luck! As a fellow 850 Spider owner I'll tell you, you have a lot of work and even more fun heading your way now
Couple other suggestion and please forgive my impudence here:
Check out FiatSpider.com, they have a small but good Fiat 850 forum there (as we do here) and check out the Yahoo Fiat 850 group. Be careful there, there are several make sure you join the one with several hundred members and "lots" of activities.
Of all of our 850 vendors probably Obert's shop is the best on inventory, Midwest Bayless is really good too. Mr Fiat in Atlanta is the only place I've seen in the US with NOS and reproduction parts (seat covers, dashes, door cards, body panels). Mr Fiat is very expensive, but when you have a monopoly on new stuff, it's to be expected.
I would finally suggest you not sell your Racer stuff, especially logos. (Unless to me
)
Jeff Stich knows more about the 850 series than I think anyone. R&D Automotive (see You Tube) is the main group racing 850's if you decide to go that route. I'll shut up now.
