Thanks Joe, I had the Revell chassis under the Mustang I'm building. I decided to go with the Tamiya set up for better detailing as I'm thinking of opening the car up a bit, (doors, rear hatch area, etc) I found out getting into the Tamiya chassis is that it seems a bit wider than the Revell one. I was hoping that someone had the Tamiya built to give me an idea of the width but I decided to mock up some of it and found out I have to cut and narrow the upper and lower a-arms to keep the track width under the body......
