/6 to V8 questions

O.k.
What you are looking for is a '73 to '76 318 auto a body complete as possible, preferably running and driving but a little rusty for under a grand. I would get a 4 door so you can to keep costs down. Hopefully it will have a 8 1/4'' rear diff in it too!
Refurbish everything and re and re.
Good luck.
