If the stabilizer has been on the bike since new I would spend the 40 and change it anyway. It's been takin' the shakin' for 11 years now, right?
other than that, I really don't have the answer to your squeak question but I just wanted to say, it's nice to see a question that doesn't have the word bob or street in it anywhere.
I ride a 93 FXDL so I know what it's like to try and find parts for an older Dyna. Most of the part numbers I go to the dealer with are obsolete. Makes it kind iof a pain. You are in a better position than me due to the changes made in '95. I find Dennis Kirk to be a good retailer for most things. If you're looking for cams etc I havn't seeen a better price that here
