Hey Brad,
I've already got plans this evening, and tomorrow I'm back down in Surrey to try and resolve my exhaust issues.
Otherwise I would have come over to AT LEAST make cups of tea/coffee
I tend to snap bolts as well but always willing to learn and I try what I can.
It's worth getting the Nissan stuff, the gearbox feels better on it, and try some molyslip as well if it needs it. But for now, I imagine whatever you can find will do.
I'm sure you've spotted but if not:
