What Transmission is the out of?

I have a K 20 72 four speed with 285/75/16 tires with 4:10 rear end. The speedometer shows 8 to 10 miles slow against a GPS speedometer app. This is a 20 tooth driven gear so I bought a 19 tooth driven gear but I guess the driven gear I bought is for a different transmission than what I have.

Could someone take a look at the photo and or tell me what to look for to determine the transmission I have.
