G'day Ross,
How are you? Sorry I haven't been in touch.
When I do my clutch's, I do it by eye, after pulling the gearbox's and clutch's out several times it becomes second nature and never have had a problem.
My close ratio box blew up the same way and it was the diff carrier bearing's exploding from axle tramp.
Blew a hole in the diff housing, bellhousing and soaked the clutch in gearbox oil and even dented the firewall!
Another common fault is the standard diff ring gear rivets letting go and doing the same damage.
