My suggestion is return it, and buy an EA tooth bar. That's what I did. I ordered a Titan one based on the attractive price. When it showed up, the bar was black, and all of the teeth were light brown.
When I contacted them, they were willing to reimburse me for the cost of a can of black spray paint... Because that will, of course, hold up to repeated use...
I said no thanks, and sent it back.
EA was a pleasure to work with, double-checked all of the measurements I needed, and sent me the exact size I needed.
When I bought my middle buster, I didn't waste my time and just ordered from EA.
Sometimes you can save a buck, but oftentimes it isn't worth the hassle. How much is your time worth to take it to a shop, etc. to make it right, versus just paying for what you need and not having to mess around?
If you're retired and have the time, maybe it's worth it. Maybe not. Your call.
