I think Bob is correct. You can use all the brackets, but would have to use all 69 pulleys to make it all line up together. I had a similair problem where someone put a non 69 WP pulley with nuts behind it to push it out towards the front on mine and I went looking for a correct pully and either I couldnt find one for a 69 with A/C or when I did find a stock one they were very expensive, I even tried repro and couldnt find one to match. Thats why I went with a complete set from CVF racing, turned out to look better (for me) and they all matched up. Off course if your looking for a stock look, which I think your past that since you went with a vintage A/C I wouldnt go that route.
