Matt, you need the roll restrictors. You might see what they look like in person.They might be quoting you motor mount prices?..? Your motor mounts are on the left and right side of the engine, you can see them from opening the hood.
The roll restrictors are on the underside on the front and rear of the engine. See my pic of the underside there?
If that's the part and the price they're quoting you then I'd get the entire piece. I've never heard of an insert for a roll restrictor.
See what they want for the entire roll restrictor...
Good luck!
