Freeze plug

Hey,
I have a 1987 Ford Escort GL with the 1.9L gas engine in it. I am trying to restore it after it sitting in a field for about 10 years. I found out that someone has removed the freeze plugs or the coolant plugs from the engine in order to let all the radiator fluid out. I found this out as I was trying to poor water into the radiator to see if it leaked or not, and as I filled it up, I noticed all the water pouring out from between the back of the engine and the transmission in the bell housing. Anybody know if there is a plug in there or if there is another plug somewhere that would seal that up?

Thanks.
