is this because you have a Mk2 Z sitting in your garage as well?
Ive tried Alex but he has also said they are getting quite hard to come by; sarah, i will look out for your pm too
and yes, i am chasing the holy grail of the 50bhp - dont think i will quite get there though but i will have a go!
I have it as I had a GT4 zed that i put a pop charger on and flung the airbox in the garage........seems they are quite desireable now
