Hemiman, the main issues with the original are, the wheelbase is too long it's 4.25 that needs to be about 3.5 for 1/25th scale. The car is also too tall, the body itself with no wheels is about 2.1" tall I cut that down to around 1.75" I also reduced the size of the opening in the nose and reduced the length of the nose by about .2". I used bits of a Grant King frame to move the the front axle back and the rear axle forward to achieve the 3.5" wheelbase. I also filled in the openings on the fuel tank area sides and bottom as well as altering the roof angle a little. Those are the big changes, I'd love to see other people do this just to get their ideas on the project, I have a couple more bodies to modify and I'm always looking for new ways to do it. I'm currently working on the T style modified and will be posting that soon, maybe later today in fact.
