I was pretty sure there was a pin index on the couple I did. Unless it's close enough to hit something and scrape I doubt a misalllign is causing the squeak.

Look at realoem.com for your car. Find the part and drill down to detail it will show the cars that used the same part. Fun to see some parts that go back into the 70s
