I'm building a 1/16 M48 Patton. I use a 21st Century M48 model. Now, I intend to install a Henlong 1/16 M26 or, M41 gear box,and drive wheels on my M48. Can someone tell me dimension of 1/16 M26, M41 drive wheel (width , diameter)so that I can be sure it fit my M48 tracks. Also I'm need the length of their track. Thanks for advance.
