Thanks Richie,
I need to fill in the edges wiv some styrene rod as the side grills are .5mm narrow, the pics just show them pushed in temp, I got to take the carbodies off again to fit the fans back in, but I dont think the smoke units will work again, sothe fans will not get wired up, I need somepics of the inside of these now as you can see right thro and cant find one of the engine blocks,
