How much is a 4 speed core worth?

I have 4 speed out of (i think) a 69 roadrunner. I cant remember the spline numbers that make a difference but its the less desirable of the two. Its a core and will need to be rebuilt. I know its not an A body, but I thought someone might no how much its worth. Also anyone interested in buying :glasses8:? thanks
