Keith, No sooner said than done.
I will look through the various manuals I have on the P30/P and see if there are any cert drawings if not I will take some photos when the wheels come off. I am in the middle of a GV fitting at present so it may be a day or six!
Likewise we are busy here and my own project/maintenance is on the back burner.
Interesting comment on front wheels. The turning circle may be reduced a very tiny bit as at present the wheels foul the inner body, that was my direction there, but again I will scour the manuals on geometry - it does leave that question unanswered at this time - personally, after the usual tracking/angles adjustments, I don't see a problem, then who am I?
Don't take life so seriously.... it is not permanent!
