I have the exact same Verlinden set that I am using in my M113A2 it has an updated drivers overhead panel which you have to remove the old molded on periscopes to add this part. And it wasn't hard to do it either use a razor saw to remove the periscopes on the kit part sand it then open the hatch opening on the replacement panel match that opening up with the original opening glue down and your all set.
