...I didn't like the 'Sheet-Metal Screws' holding the Front Grill on...So I went to 10-24 Steel Nutserts with 10-24 Stainless Oval-Head Phillips MACHINE Screws. Do NOT use 10-32 Fine threads, as Debris will Cause them to Gaull-up and jam.
The Nutsert head is too small for the Pantera sheetmetal holes, washers must be used, drilled for perfect fit, and Longer grip for the Nutsert. Or Nutsert with Larger HEAD (Available). Also the Grill holes, usually for a SM Screw, Must be drilled larger with a 'J' Letter drill bit, or 7mm, for clearance. The OVAL Head screw is more Pleasing to the Eye, that a Flat Head. IMO
See photos, of drilling brass washers for perfect fit. Using Washer both front and rear of sheetmetal, requires a Longer 'GRIP' Nutsert. (Not Availble)
