For a 1/2 ton or a 3/4 ton, you'll need a straight-flute adjustable reamer, 27/32" to 15/16". It's available from ENCO, part #334-1113. My catalog is a few years old, but the price there is $20.21. Use lots of cutting fluid and ream a few thousandths at a time. You can always make the hole a little bigger. It's hard to put the metal back in there when you get it too big!
