speedo drive gear (40t?)

[swing69]

Looking to get a 40T speedo gear for a 904.
Ebay has LA speedometer gear for Jeep.; Dodge Jeep 40 Tooth Speedometer Gear Long Shaft | eBay

will that work? are the gears and shaft the same? I'm going with a late 60s 904 trans

If that's the actual pic of the gear, yes, it will work. I'm not sure of the years, but "earlier" Jeeps used that style of gear before things started getting more electronic oriented. Same style as I have in my ad:

[FOR SALE] - 727/904/833 speedometer pinions & related parts

I found the green, 34 tooth gears in Jeeps, but don't recall the years.
