I have a 98 377.. was thinking of doing the same thing...
My pete had a sleeper and someone made a day cab out of it, now I dont have a seal to go to the box.. that might be an easy fix but im stumped as to what to do with the air ride on the cab.. there don't look like there is any room to keep them on the cab and still mount the box..
Do you have any pics?
thanks
