A body SB pushbutton tranny

I have a 1965 727 cable shift that was on a 318 poly. I was told it had about 1200 miles on a rebuild but I don't know if that's true. I sold the 318. I was told it had been rebuilt when the tranny was and when I removed a valve cover it was very clean, leading me to believe the engine had been rebuilt. I'll sell it for $150 but you have to pay shipping, which might be expensive.
