No, no fouling of the side panel or bonnet - everything shuts as it should.
I've completed the install today. I used the output rod that I turned in engineering class - it's a bit of mild steel to these dimensions:
It replaces the one that came with the servo - I reused the knurled locking ring though.
I wound it out and kept trying the master cylinder with the adaptor plate bolted on in place until I could make plate and the face of the servo touch with no resistance on the cylinder.
Then it was just a case of running new fluid feed lines (the old ones where two short), putting the heat shielding back on and voila:
I haven't had a chance to road test yet, as the dashboard and centre console are out whilst I wire up my starter button.
