does anybody know what the specs are for they pickguard?

bevel degree and thickness?

maybe another site or something?

dunno forsure about LP Jr but standard 3 ply pickguard thickness is .106 inch and bevel is 45 degrees

if it's 1 ply it's probably .083 or .059 inch thick

doesnt really matter though as long as its not too thick to interfere with anything
