Again - do you want a 3/4, a 4/6, a 5/7 or do you want to lay frame or rockers? It all depends on HOW FAR you want to go. A 3/4 will be the cheapest if you do it right - Beams up front and axle flip in rear - under $400 unless you can get the beams from a friend or something. Flip kit is super cheap - $50 or less.
