Mike, Pinblock too thick...rebuilder probably thought more pinblock, better for tuning...forgot about the drop screw...well now can think of only three possible solutions...(1) can drop screws be filed and cut to regulate and pass under pinblock (yes)(no)....(2) grind off excess pin block....can't be done in customer's house... ( 3) remove pin block.....MAJOR PROBLEM>>>BIG MISTAKE ON REBUILDER'S PART.. On a few occassions I have be able to file drop screws and cut slot for regulation. Tommy Black Decatur, Ala.
