As far as I know they only raced the Mk IV at only two races in 1967, Le Mans and Sebring, and only 6 cars were built, 1968 and 69 they went back to the Mk I as the rules were changed to maximum 5 litre engines and Ford themselves got out as a factory team.
The display Rubber Duck ornament that came in the MPC Convoy Rubber Duck Mack kit isn't five inches tall, more like two...I have one on my desk form the original kit I bought back in 1978-79...but it's not for sale. If you want one for a kit you could maybe talk to Dave at AITM, he does a resin kit of the Rubber Duck truck including the hood ornament, not the display ornament, it's the one that fits the kit.
The small tires for the front wheels on drag racing cars are called "Front Runners" and they are specially made for racing purposes. Several Revell, Monogram and MPC drag racing kits have front runners but they can also be found on the aftermarket.
The only kit I have ever given up on is this one. It's a modified reissue of the Orange Crate kit and if the Crate is difficult this one is even worse as it doesn't build up the same way...well some things are but other things doesn't. I bought it back in the 70's and I thought it looked cool but it was unbuildable at my age, I think I was 13-14 years old at the time, I've got one more (and a couple of the Crate's) and will give it another go when I feel up to the challenge.
Okay...but the holes are not that large between the spokes as you can see at the picture below so I don't know if they will show that much on a model. Painting techniques...the 63-64 wheels are bare with polished spoke and rim edges and the cone and spinner are chrome, so I don't know but I would probably paint between the spokes with aluminum paint and wipe the edges off. The 65-66 wheels are darker between the spokes so I would use a darker grey color for them.
You can buy HRM stuff through Replicas & Miniatures Co of Maryland, Harold Bradford from HRM and Norm Veber from R&MCoMd are friends and and both live in Maryland, and I have bought HRM stuff from Norm before. Strada Sports and Island Collectibles also usually carry the HRM stuff. But Harolds wheels are 1:24th scale and would be a bit too large for a 1:25th scale model, 15.5-16" instead of thje standard 15".
@Raoul: The kit wheels look a lot better with the 62 Impala spinners.
Nice, I built that one a long time ago back in the late 80's and I still have one more in my stash. Wich version are they?, the rarest are the first issue with Air Ride, the later ones had Walking Beam.
I built the Revell AG KW K100 flat top a long long time ago...back in the 80's when they first came out...and I want to have another go, so this is welcome as the prices on ebay for all Revell AG trucks are ridiculous. The only difference with the flat top and the Aerodyne is the roof section wich is a separate piece from the rest of the cab, the top bunk is also included in the flat top kit if I remember correctly and I think even the roof windows are in the kit. Maybe they will reissue the K100 Aerodyne soon too.
IMHO the best looking 427 SOHC so far is in the AMT 33 Willys kits, the one in the MPC Malco Gasser isn't that bad either, the one in the AMT 66 Galaxie is also workable. The SOHC from the Jo-Han Maverick is a hybrid as it shares the engine block and heads with the Boss 429, it does not do that in the real world...the 427 SOHC is based on the FE family and the Boss 429 is based on the 385 family, two completely different engines, the valve covers/cam covers are not the correct shape and the plug holes are not in the right spots ( a common fault with many model kit SOHC's)...but on the other hand...no kit SOHC is perfect. But this thread is kind of old...allmost 10 years...so the original poster has probably allready chosen the engine.
Nice build, a AMT R-series is a lot better than the old Ertl kit would have been as the DM is totally wrong, and you have used the only usable parts from it.
If you go by the movie sound track the "Rubber Duck" truck would have had a Detroit Diesel 2-stroke engine, but the pictures tell a different story, the truck has a dual intake tube air cleaner so the engine should be a ENDT 676 "Tip Turbine", and you hear the 4-stroke engine in some places in the movie where they haven't replaced the sound...same goes for the air horns, you don't get that high pitch tones that are in the movie sound track from the long horns the Rubber Duck truck has, they have a much lower pitch sound wich also can be heard in some places in the movie.
