Mk2.5 Style Bar with factory windblocker

[Retroglide08]

I have just got myself a tidy MX5 MK2.5 and would like to fit a style bar. I have seen some which require the factory windblocker to be removed.
This one has caught my eye from MX5 Parts. Would anyone have one like this fitted and did it require the wind blocker to be removed
