TH-400 Speedometer Gears

[SlickGTP]

Does anyone know where a good source of decently priced speedometer gears would be? Ideally I'd like to find a 21 tooth drive gear, but that's unlikely from what I've seen looking around. My other option is to keep my 1.3 ratio adapter and run a 39 tooth driven gear for which I'd also need a new housing.

Ebay is looking like my best bet, but figured I'd ask around here before jumping in.

Thanks!

I went to my local transmission shop and they had the gear I needed in stock. They were willing to order other tooth counts as well.

Cool... Guess I should find a reputable transmission shop close to home.
