The provent is a good buy. Western Filters in Aus has all the parts you need including the reducer in a silicon. Pic below.
I have a bugger load of parts coming in the next 2 weeks. Weeks kit 1 and 2, updated fuel filter head, new map sesor, new plugs, new thermostat and the GDE tune...soooooo looking forward to it!
Still have a rattle that is annoying the shit out of me but can not find it. Will look more when I do the above work.
If not the whole front end is coming off
