Meaning that the tool is too long? I'm about to start this project myself, my A-belt also has some cracks in it and they are of unknown age anyway.
If one is not experienced in setting the belt tension via feel.. what can one do to test belt tension? Are there easily aquired (read inexpensive) tools that will do the trick.
Also, I need to order some other tools from Snap-On and just might order the 12-point from them. I did not see in any of the posts what size it was. 12mm, 10mm, 90mm (OK, I know it's not that big).
Thanks for the detailed writeup WITH pictures... Since I managed to change the caps and rotors myself (what a PITA to get that lower screw on the bottom cap) I think I can handle the belts. I think.

The tool you want is a 10mm, 12 point star bit. Mine arrived a few days after I was all done and I haven't bothered to check it would fit on a ratchet and still into the alt. shaft. Honestly, just buy the the cheapo Lisle bits from the local car parts store. I have all the metric star tools and have used them maybe once per year at most. The 12mm one is good for flywheel bolts. One of the smaller ones can be used for some CV bolts. The Snap-On stuff, while nice, is way overkill for jobs you won't do but every few years.
I'd rather have the belt too loose than too tight. If it's way loose, you might hear it squeal when you blip the throttle. I can live with that. Get it too tight and you can easily bend your alt. shaft. Best bet is to just note how the tension feels before you remove the old belt and try to get the new one to that feel.

Also suggest a flexible magnetic pickup tool. You will drop something down there at some point.

Also interested in hearing of any cheap tensioning tool solutions...

I will be changing my belts this weekend. The belt tension is adjusted by adding or removing shims between the pulley halves, correct...? More shims = less tension...?
