I'm also glad to hear you succeeded. I will throw in a little tip that might come in handy for someone else. Slide a piece of discarded, or not discarded ratchet strap around a stubborn filter as close to the threaded end as possible, then using a long needle nose pliar or figure something else out to wrap up in the doubled-over strap so it pinches the snot out the filter as you twist strap with a 1/2" drive ratchet, or anything else you can fit in there, and it will twist it off. I have never failed using this method. I have never even had to put sand paper against the filter. My HD Dynawideglide oil filter is in a ridiculously tight spot and this is the only thing I have found that works. One of the gents (?) posted a hyperlink earlier to a filter wrench that uses the same principle but why buy when you can improvise?!Glad to hear it - in some of those places, it is simply a nightmare to get any tool in place to apply that much torque to get the filter off.
