This car probably ran on alcohol instead of nitro, putting it into the (lower) Pro Comp classes.

I'm surprised there isn't a company in Canada doing those conversions.

I was about to say that. My mom had a set of those on her '77 Cutlass Supreme. The original tires were put on with the whitewalls out, but we talked her into turning the next set to the inside and it looked a bunch better. The AMT '66 Mustang wheels are a different brand but are probably the closest thing to be found. They are NOT in issues produced after the mid-Eighties however. Adding some chrome rings to the front of them will make them more closely resemble the Appliance wheel.

Pat Ganahl later built a '60 Plymouth wagon that appeared on the cover of Scale Auto. I'm pretty sure he also built a model of the John Milner Deuce coupe in an article that appeared in Street Rodder magazine. This was around the time the movie was current, several years after the AMT '32 coupe kit was (at that time) last issued but prior to the mid-Seventies reissue.

I saw the Lancer chrome parts tree (unplated) among the test shots in the short video. I didn't see anything of the Valiant though.

Can't think of one. Chevrolet had the Malibu Laguna S-3, but that was available long before the Can Am.

The rule insisting on using the "factory/showroom" suspension design ended with the downsized cars in 1981. But a lot of the early downsized cars' chassis were cut down from earlier ones, as the more modestly funded teams waited on the big dogs to sort out which chassis layout was best. It's probably a toss up when it comes to the earliest downsized Mopars, but if I were guessing I'd go with a cut-down longitudinal torsion bar front/leaf spring rear setup. Petty was the last bucks-up racer running a Mopar, after he switched he sold off a lot of his stuff to the other racers.

Nope, it has the '78 style rear window.

The blue custom pictured is indeed based on the '78 pace car. I still have the pace car (I collect those), and had the custom at one time.

The "logistics" on the trailer door is hilarious...

Anything with the ammonia odor will have adverse effects on any model kit plating (vacuum metallizing) that you may wish to save. Even if you find masking material that won't affect the plating, whatever you try to use to remove the unmasked plating will probably creep under the masking medium. I'd hand (brush) paint the areas that need to be painted. If you have to add something to the paint to slow its drying and lose the brush marks in the process, then do that.

Cast iron or aluminum?

The wagon taillights were the more popular ones for customizing because they bolted right onto '55-'56 Fords and Thunderbirds. Nobody really used the Mercury passenger car units on other cars, so with no 1/25 scale Merc kits there are no taillights available.

'61 Ford Galaxie.

That's a parts pack dragster. I'm pretty certain the newer Slingster was tooled and produced overseas, if so then Atlantis didn't get that one.
