The only inherent problem there is the mixing of scale issues. Has anyone actually put those wheels under an AMT Mustang to see how large they look?
Here they are on an MPC '84.
Stock tires from the GT convert kit:
On a lower profile set of Gatorbacks. I don't remember what kit these came from at the moment, but I have four of them.
Compare to my '92 LX driver with stock size 225/55/16s:
Almost exact. Ride height and a slight adjustment to the shape of the wheel well would be all it takes.
You absolutely sure about that body molding color year, Mike? Because the factory literature I do have lists 91 as the first year for the LX Coupe getting body colored side molding.
The Pony wheels in the 1/24th scale mustangs scale out to 15" versus the 16" they should be. So, by putting them under a 1/25th scale car, they will more closely represent the 16" wheel they are supposed to be.
Positive on the moldings, many have been painted body color over the years for an update. I just touched on the major visual changes from year to year, there were many more: Seats and headrests, interior color and upholstery patterns, paint colors, rear seat shoulder belts, door panel pockets, etc. A little research would be required to make a year-accurate model.
