rebuilt SB 727 tranny

I have a rebuilt SB 727 tranny that has never been installed yet. The numbers on it are: PK 8898866 5437 5003.It was rebuilt to be put in my sons 73 Duster he is restoring, He decided to put a 4 speed behind the 340. I am selling it for $500.00. I am located 35 miles south of Cincinnati,Ohio. I have 3 pics but it would not let me upload them. E-mail me and I will send pics if interested. I managed to upload the pics on the B-body side under parts for sale.
