Chris, in the end I was stuck with the ford 5speeder, but I wont pretend I'm too happy with it, The box has been in and out twice with clutch problems, the first time out it was because the diaphragn spring plate ruptured. Half the fingers worked and the other half just went all "floppy".
And to top it all the pedal has started bouncing around under my foot AGAIN! Works OK but feels absolute sierrahotelindiatango.... Again!
Might have it out again next week! [no please no sniggering at the back!]

I have to say BigH, they swirls don't usually cause concern, just that the head looks so perfect otherwise, tha knows.

Bill
