Doing some more research tonight (as I can't sleep :angry: ) The kit drive train lay out is of the 66 Mustang that Dick Brannan drove, not the 65. Not a huge deal, but the 65 had either a four barrel carb or dual four barrel carbs. The kit is fuel injected engine intake for the SOHC engine. The transmission is a standard and not a C6 automatic (I'm thinking Brannan did not run a standard trans in the Mustang, but not sure). Dash is wrong to for the 65 as it should be the stock Mustang dash. :hmmm Body is correct for the 65 and early 66 versions. The decals are not correct for the 65 version, a couple things jump out here, one the dealer name is in black and not gold, the "Bronco" name is out lined in black, it should be red. A couple more things are, the car was red first, then the gold and white, then some time a large white strip was added to the trunk lid and roof and a split strip was on the hood. Also at one race (or photos) the hood is black or looks black (could be the angles). Not sure why the wipes are molded to the body, these cars never had wipers. The rear wheel opening are correct!!!!! But no the front, fronts are in stock location and should be forward about 4 inches. The roof vents should not be there, will have to be removed and windows made. The hood has a huge cut out for the injector stacks, this will have to be filled for the 65 version.
Okay with that said, these were hand built race cars by Holman and Moody to look like a stock version Mustang, kinda. In 1965 Ford factory racers were running Falcons at the start of the season then moved to the Mustang. These Mustangs were built to counter the Chrysler altered wheel base cars. Race cars will always evolve during a season to stay competitive. Another problem is everything is done is secret so not many photos. In 1966 one of Brannan's Bronco Mustangs was destroyed in a accident. After that he was in a long nosed Mustang.

Magazine page with a different prototype, I think this might be Gas Ronda's or Hubert Platt's car
