After my last valve adjust, I was taking things apart to put in my stick coils. My #2 boot fell right off the wire, same as yours.
Easiest mod you can make. Also added the Snarf reed valve covers and took out all that plumbing as well.
i just want to make a statement, and before I do I will say The stick coil kit Tony is providing is top quality, and it does offer some advantages, reduces clutter, and will provide a hotter spark.
with that said, if you are in question whetehr your coils are going bad, you really should do the examination on the wires, and even remove the caps and do a pre-emptive trim on the wires and re-install, before going nuts.
The repair costs nothing, and the OEM coils in normal condition offer everything you need to operate the engine correctly. I believe a lot of the "coil issues" people have had are directly tracable to those wires and caps being compromised, so, as I said, it doesn't cost you anything to fix that first. If you still have issues, then by all means jump on the new coil bandwagon.
