So, had a call from the garage fitting my clutch & flywheel today. They have had a problem with the Sachs flywheel I got from Darkside Developments. There are apparently welds on the back of the flywheel (which is otherwise identical to the OEM one removed) which are fouling on a plate between the gearbox and engine...
Phoned Darkside and explained the situation and they spoke directly to the garage, they have looked at one of their other kits which also has these welds but say they have not heard of this problem before.
Unfortunately it means the gearbox is going to have to come off again...
The garage is going to take the flywheel out and then decide if grinding the welds down is the best option or if it needs to be sent back to Darkside and replaced.
I am hopeful that Darkside will help cover some of the cost for the gearbox having to come off again but I know that is probably just wishful thinking.
Inconvenient to say the least...
