8 3/4 western pa HELP!!

I have a center section only: 4.56 with a spool -- $500 (you can pick up) I'm in Pittsburgh.

i ran this in my 71 Demon with a built 340 and it ran great. Only reason for selling is I quit racing to build my Demon in a pro-touring car and will be selling this for a set of 391 suregrip.

Let me know.
