The original aprons fit but because the previous owner cut the ends off with a torch to allow the exhaust pipe for stacks .They were cut right were they curve around the cab corners. The aftermarket one I have is for the passenger side I got it off eBay so don’t know were it is from but still has sticker on it .the aftermarket one hits the cab corner at the top but is okay by the running board ,so it looks like it has to be cut and reshape to curve around the cab corner.My cab corners are original and the box is original with original fenders .The running boards are gm running boards from different truck .
