That's a job I never want to do again, allthough the results were fantastic. Took 'bout an hour and a half, then went for a ride to see how it sounded (it's 17 deg here, very short ride). Tools needed, Drill, couple of 1/4 in drill bits(only broke 1), a BFH, a bigger BFH. Fanfreakintastic. Drew blood, but nothing broken, that's a good job. Over the first hurdle, now where to go? AI I suppose.
