For the larger clutch head bolts, like the ones that bolt the rear fenders on, and if you have a spare tire holder on the side panel, holds that on too,get clutch head socket attachment for a 3/8 drive rachet. I just got mine from Snap-On and worked great with a 3/8 drive breaker bar to remove the old bolts.

The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself." - John Stuart Mill (1806 - 1873)
