Big . . . I laser burned a couple of 18GU plates to put behind your dash radio opening that have the correct hole locations. The idea was that if your dash was really butchered, you could spot weld one of these behind the dash and it would give you the right size opening and hole spacing for a decent way to mount a stock radio. You still have to patch any big butchering on the front side if the radio bezels don't cover. The first couple I made were not perfect, but I plan on modifying the drawing / program and burning a few more in the future.
