What do you want to do with the car? Street only, street and strip, strip only? Is fuel mileage a concern. Is the engine in good basic condition? What kind of budget? Do you need to things a little at a time, or can you do all the mods at one time. We need a little more info.
The rear should be a 7 1/4, if it has not been changed.
