Anytime. I am running a 9" out of a 57 sedan. It bolts in w/o any modifications. I should revise my last comment on mods for the headers. I cut out all the crossmembers under the floor boards. the tranny member and the 2 supports that run diagonal. It opens up the underside alot. send me your phone # to this email kokobeach@cableone.net and I can give you a call. I have unlimited on my cell so it wont cost anything
