"I actually have the new belt and all the new seals sitting in my garage. All I need to do is order the thing that holds the crank still while I get the crank pulley off."

Scott,

If you find the belt has skipped, you don't have to wait for a crank holding tool. The "Rope Trick" is just about as easy and quick as the tool. You can do a search for it here, but the basic steps are simple:

1 - Pull plugs and rotate crank to #1 0° TDC Compression
2 - Verify #1 and #2 valves closed - look thru oil fill hole, cams pointed upward.
3 - Rotate crank about 90° past TDC
4 - Stuff 3' to 4' of clothesline into # 1 plug hole, leaving 6" outside
5 - Use socket, breaker bar, and pipe extension to loosen pulley bolt
6 - Tighten bolt the same way, but start with crank about 90° before #1 TDC Comp.

AFAIK, this is the only "trick" holding tool alternative that allows tightening the bolt to book spec of 44 lb ft, then an additional 60°.
