Nice work as allways Sean...I have one of these too and one of these days... Be sure to fix the air cleaner too as most of the outside scenes truck appearently had a Mack ENDT 676 Tip Turbine engine wich has two air ducts, one for the engine itself and one for the aftercooler.
As far as I know the St Louis Dumptruck truck is one of the trucks used in the movie and so is the tanker they had. They also had one surviving Duel truck but I have read that they are both sold.
Electric cars will kill the sport of auto racing completely and chase off spectators, the sound of the engines are a crucial part of the experience together with the smell of hot oil and exhaust fumes of racing gas, and it should be loud. For example Formula 1 has lost much of it's appeal since they went to quieter turbo V6 / hybrid engine packages and many I know will not go to another F1 race until the "old" sound is back. There are a series called Formula E with electric cars...I have seen a couple of races on TV but it isn't for me with the engine sounds gone.
I got my copy of Model Cars #199 November 2015 in the mail this Monday and the magazine came in a transparent plastic bag this time. The magazine is great as usual but I wasn't that impressed that they put the address lable sticker on the front of the magazine cover in the lower right corner, they could at least have put it on the back cover, or preferably on the plastic bag itself...earlier I got my magazine in an envelope and the address lable was on the envelope and not on the magazine itself.
Yes, the wheelbase differs and even the Mustang has different wheelbase than the Falcon, but as mostly everyone know the Mustang is still based on the Falcon platform. The 62-65 Fairlane and 62-63 Meteor chassis are quite different from the Falcon based cars and even tho' the whole front suspension are similar in design as the Falcon based cars close to nothing of the hardware are interchangeable...as I own a real 64 Fairlane I know that's the fact, I have learned it the hard way. Here are wheelbases for 60's Ford's and Mercury's Ford 60-65 Falcon 109.5" 66-70 Falcon 110.9" 59 Fairlane/Galaxie 118" Frame 62-64 Fairlane 115.5" Fairlane/Meteor, 65 Fairlane are 116" but still has the same chassis as the 62-64, the rear axle is ½ " further back. 66-67 Fairlane 116" Falcon based 60-68 Galaxie 119" Frame 64½-70 Mustang 108" Falcon based 71-73 Mustang 109" Falcon based 58-66 Thunderbird 113" 67-71 Thunderbird 115" Mercury 60-65 Comet 114" Falcon based 66-69 Comet 116" Falcon based 70-72 Comet 117" Comet/Maverick 67-70 Cougar 111" Falcon based 62-63 Meteor 115.5" Fairlane/Meteor
As you see the Fairlane has 1.5 inch longer wheelbase than the Comet and if you want to build a correct replica you can't go by the wheelbase alone when to decide what chassis to use, the basic design of the chassis also has to be right. So if one wants to change chassis under a 1964 Mercury Comet and want to be correct a Falcon based chassis changed to the right wheelbase is a better choice than the Thunderbolt chassis as that is what the real car has. I don't exactly know where the length in wheelbase differs on the cars based on the Falcon platform, if it's the floorboards or if it's the front subframe that are of different lengths.
I have a real 1964 Ford Fairlane 500 Sports Coupe and the '64 Comet has a different chassis than the '64 Fairlane, the Mercury Comet is based on the Falcon platform (wich also goes for the Mustang), and the 1962-65 Fairlane shares it's chassis with only the 1962-63 Mercury Meteor and it looks different than the Falcon/Mustang/Comet chassis, specially the front suspension setup and the spring towers under the hood. So a Falcon or Mustang chassis is a better choice than the Thunderbolt chassis if you want to be correct...or as Kris said, wait for the '65 Comet and you will get the correct wheelbase. The 1966 and forward Fairlane and Torino was based on the Falcon/Mustang platform tho'. Another thing, the Thunderbolt chassis and front suspension isn't right for a regular Fairlane either as that was modified to fit the big FE 427, anything larger than a 289-302 and maybe a 351W engine needs severe modifiactions to make room for it to fit in a real car.
