Good question. The USA made Fender '52 RI pat pend bridge plate sells for $12 retail and with saddles maybe $29? Aftermarket/ boutique brand names get $100 for a nicer version of that $12 plate. Many choose Wilkinson to save $2 on the bridge setup and get a cheap compensated saddle set. Maybe Fender just doesn't see value in creating a stock # for individual saddle height screws in different lengths? IMO they should fit every new bridge with the two E height screws a little shorter, but with each player setting up their guitars to personal preference, no standard would fit every application. I like the fact that Fender sells good parts at cheap prices without compromising quality, or at least they make the new bridge as good as they were in '52.
