I just installed mine and I used the phrase mother f$$$er about 500 times. I can't blame it all on the unit, maybe none of it, but it is difficult for a guy my size to get in the trunk (5'11 240). First my cordless drill was about dead, then my wife brings my 3/4 drill which wouldn't fit in the trunk (what was she thinking). OK so I got a drill that worked, then the bit was pretty dull. 7/64" is a little too small, so you have to ream the hole a bit. Finally they went in and it worked OK.
If you have a small jockey in the family, invite him over to help. /phpBB/images/smiles/icon_biggrin.gif
