Any question answered...

if anyone is interested, evans fixed the pedal situation for free this morning (thanks evans!) and they couldnt do it with their regular spanner, they had to go downstairs and get a massive one, and even them it took them a little while and some grunting. so at least i wasn't just being an idiot. lesson of the day is buy massive tools, small ones are too puny.

Lesson of the day is use lubricant/ anti seize on the threads of the new pedals you have fitted.
