TH400 Transmission Speedometer DRIVE Gear

[Joseph S.]

I have a 1968 resto-mod with a TH400 Automatic Transmission. I am trying to source a 16 tooth (orange colour) DRIVE gear for the Speedo. The GM part number is 8623311. I have the correct DRIVEN gear that will give me the accurate speedometer reading.. Any information would be helpful..
Thank you,
Joe

eBay, Jegs, Summit do a google search.
