Moonlight,
Yes, you caught a typo in my prior post. DRIVEN is the correct term. I’ve edited that post.
Nice research. I’ve not found a 23 tooth DRIVEN gear from other vendors.
Your speedo will work fine with a 23 tooth but will be a little inaccurate on the high side. Probably not much to worry about and the % difference will be minimal.
You might need a longer speedo cable. Your drive shaft will need to be shortened by about 3”. I used a worksheet from Denny’s Driveshaft on the internet. Worked perfect and gave my drive shaft shop all the info needed.
