69 superbee tranny need response ASAP please

[andy69tanny]

Hey fellows. Here is the story. In my garage has been sitting for about 20yrs a 4-speed that I was told cam out of a 69 superbee (engine unknow). It was pulled rebuilt then bought by my father over 20 yrs ago and hasn't been touched since. I just happened to run into a guy with a car I have been looking to buy that happens to be looking for an old mopar 4-speed. I really need to do some homework quickly because I have no idea the value of this thing and dont want to get screwed, because I am really only looking to get an 87 beet up daytona that is not even running (summer project)out of this deal, I was hoping someone on here could give me a ballpark estimate on value, tell me exactly what it came out of... what it will fit (any info!! or even just poing me in the right direction). I would be incredibly appreciative. The big numbers I pulled off of it are....
one the main part: C 96561H and C 95664W
on the tail shaft: C-86707J
It has a 23 spline input.
Thank you in advance Andy
