Wow - i didnt realise there were any sprints in the U.S ! did you import it yourself? anyway here is a link to the supplier page from the aussie alfa club page. two of the best places for what your looking for are 'turin imports' and 'the spare place' - both in the south australia bit...
btw post some pics of your sprint and zagato!
