Chad - If and when you do find those Saver parts shoot me a PM with a price. I May take you up on that if the price is right.
Man I went and ran a pack through this weekend on the newly rebuilt diffs. CRAP, I locked/blew the rear diff on the first run. Nova cup actually failed. The pins that hold the 4 spider gears mashed into the sidewall on the Diff Cup. Therefore locking the diff and chipping some of the gears teeth. But you should have seen the "doughnuts" I was doing. It was literally like a Gyro, the faster I gassed it, the faster it spun. Spun so fast It was just a big blur.

Crazy.
So new Bevel gears are OTW and I will just go back to the Losi HD cup (on the rear). What a shame. The CD is holding up OK.
