Thanks mate, It fixed the vibration, Yay! I may do the same with the g/box crossmember, that way everything is captive and will last for a very very long time.
Marugen Shokai works style rear spoiler finally arrived. Wow, it was worth the wait. Best quality fibreglass I've ever seen, finish is great and looks ready for paint straight out of the box Those others that ordered this will be very happy campers!
With a bit of luck I'll get it painted this weekend
