Took it to Bimmerfest... Then promptly dropped the window regulator... With no tools.
Then did a quick drive through the race pits and coincidentally found the cars PO! He had been doing a track session and had every tool i needed

. Somehow the securing clips came free and the glass fell off the track (I stupidly reused the original ones), I had replaced the regulator a few months prior too. Needless to say I'm thankful I got it all fixed up for the day. PO saved the day! Now to get some new clips on tuesday.
