I had a tough time doing my rear tire so I wouldn't recommend you even try.  But getting the wheels off you should be able to do.  And what happened to that cat bait you used to drive?  JagUare or something.

I can understand why the HD dealer don't like you.  He knows you don't need him.

I would think any foreign bike dealer would help you, but you might try the auto guys.  just know how to do it yourself and make sure you watch 'em so they do it right.
