What type transmission do I have?

I have a 73 Bronco, automatic transmission, with an after market B&M floor shiftertha the PO installed. I think I have a C-4 but am not sure. I got these numbers off the passenger side of the transmisision and what does it mean?

Sounds like C-4 numbers at least its a 73 p/n cant say for sure my parts interchange manual didnt have that number. but count the bolts on the pan if it has 11 its a C-4 if it has 17 its a C-6
