It sounds like you have the Skif kit. It is a good starting point, but I recommend the Eduard p/e set and replacing the wheels and tracks. Armo and Sp Designs both make replacement wheels and SP Designs also has replacement tracks. I believe Fruil also makes a set of aftermarket tracks for the MT-LB. HTH
