I've got one mounted on a Mighty Mite body, but I scraped a bridge-sized rectangle through the finish and the "flamed maple" veneer then mounted it to the raw swamp ash with 1 1/2" screws... I remember thinking "well that's staying put." I do have some vernier calipers and a ruler, I could measure it accurate to 1/32". Or maybe 1mm, it is foreign. Let me know if that'd be any help.
