Speedometer Gears

So who all carries these things? I've looked around and the previous one I ordered through YearOne was from TCI, but they don't have any listings past 31 teeth or so (I need 36 for the new rear end). I've seen that Brewer's carries them, but apparently anything over 33 teeth is made of platinum for the prices they want. Passon has them listed on their main menu, but no individual listings for specific gears (trying to get a hold of them now). Jack's Auto Parts used to carry them, but when I called about them they said they don't have them anymore. Are there any places I'm missing? I have a hard time comprehending that a part that has been the same in pretty much EVERY Chrysler transmission since the 60's up to the 90's isn't available aftermarket anymore. I'm pretty sure the one I got from TCI was even used. I paid $15 for the 31 tooth one, but the best price I've seen for a 36 is $40 USED... I don't need to know how fast I'm going for that price, lol.
