cut about 3/4 inch off the cab, looks better now. i read that the builders added 51 inches to the original, so 1/14 of that is about 3.5 inches, and that's about where i'm at. i may have messed up using the blue tamiya cab, i thought it was pretty much just blue plastic, but it has a clear coat on it, so i sanded off as much as i could. especially where the glue will sit. i'll give it a gentle wash in brake fluid before bodywork.
