I'm looking to make some Jazzmaster pickguards, but every outline and CAD file I've found has different dimensions and screw locations. I've even tried overlaying outlines over photos of Jazzmasters to no avail.

Does anyone have a JM pickguard outline or CAD file that they know is accurate? I'm looking for vintage/AVRI, not the MIJ type.

Thanks! Mel
