I thought it was the transfer boxes that was the weak point if thats what youre alluding to Dan, not the main gearbox?
Besides id expect any rebuild to use uprated parts on a well known weak point especially when you know youre not running the standard 220bhp in the future.
Nice work Beau. Love the wheels. Whats a J reg now? 92? - very nice condition for something approaching 20 years old.
