Hi Buck,
Your calipers may need adjusting because your figures don't tally with the ones I normally work to.
You'll actually find saddles for both L and FG series measure in at 73.5mm x 3mm x 8mm. My measurements are taken from a number of spare Yamaha saddles from both the L & FG series and all share the same degree of compensation.
It doesn't take much work to produce accurate bone duplicates of existing saddles and - unless you prefer to buy off the shelf - I'd highly recommend making your own.
