Re: best way to drill holes?
I feel sorry for you....when I was drilling the holes in my springs for the teflon pads I ate up 6 drill bits and never got a single hole done. I am lucky in that I have access to a HEAVY DUTY punch....you know, one of those 12 foot tall scary machines that will punch 2" hole in 1/2" steel....worked great on the springs.....
Do what John says....but you might want to try to find a really hard drill...not you local Craftsman...Also, make sure you drill a small pilot hole...you may even have to drill it several times going up a few sizes each time.
