So long as its not damaged I would try secondhand first, there isn`t a lot can affect a hood stick apart from damage - try Oaktree Garage in Wheathampstead or Harris Mayes in Rickmansworth - the former usually has loads of breakers (I got my hoodsticks, a canti rail and a new hood from there - its like Aladdin`s cave, I also came away with an Ifor top, some new rear seats and a Rapier drop plate, and I only went on spec) and the latter sometimes has MOT failures that it breaks.
If you give either a call they should tell you what you need and whether they have it.
