Query: I'd give it 0 stars but the system won't let me.

I have a saw with the specified slot size but the unit rocks. The technical service rep at Grizzly told me he'd never heard of my saw, like this is an important point, and they were not responsible for saws made prior to the start of their own company - even if the slot were the same size. They'd let me return it at my expense, and remember I'd already paid to ship it, and with a 10% restocking fee so to return it I'd lose about 50% of the total paid which the rep agreed was correct. He suggested two things that might work - build up the base around part of bars thickness or have the bar milled. Yes but this will cost me another $20-$25. So the summary is to make this work I need to put money into it. Other tools I've bought with the same specs fit nicely. So much for Grizzly. As a side note this unit was loaded with grease like you'd expect to find on an old car grease fitting. This will be my first and final purchase from Grizzly.
