What year did prevo enlarge the front wheel well sufficiantly enough to easily take and put 365s?

I know it was after 02 but before 08

How many have ever mentioned this I've never seen it discussed. This was a MACDADDY improvement for guys like me. Nobody noticed. Remember a recent post where I suggested they do this to fit 400 series super singles? Why not do it more, nobody seemed to notice they already enlarged the opening once already.
