Speedo Housing HELP!!

Need some help here... I purchased a 700R4 from some dude in Houston. He shipped it to me and also shipped what I was told was the correct mechanical speedometer housing and gear..... When I tried installing the housing and gear it didn’t fit.... The reason it doesn’t fit is because it’s too small. I’ve had no luck with this clown sending me the correct one. Now I have to buy one but not sure if there are different sizes. It’s supposed to be a 1992 700R4 (this is what he told me). Does anyone know the size it has to be or do they only make one size for that transmission?

Tranny ID numbers: CNZ179797 (at least that's what it looks like to me)

How do I know what the Drive Gear teeth is?

How do I know which housing I need?

I have a 70 Chevelle with a 454 and 700R4 tranny. It has 4.11 gears and running tire size of P245/60R14 on the rear..

I've tried calculating what speedo gears I need and housing but I guess I just don't understand....

I'm at a loss.....
