pfyc.com can get them for you. They have only the SS model listed, but if you email someone at the company, they will get you a total for them for a 2.2.
If you do a search online for them, you'll be able to get pricing from a few companies...the model number for our cars is: 12293
I haven't purchased any yet, but you can get them for $105 plus shipping I believe from PFYC. Also, if you're interested in SS lines, but don't want to spend as much, you can get Russell. They aren't bad, just not as high of quality as the Goodridge.
Modern Performance has the Russell's for cheap...here's a link:
Modern Performance: SS Lines by Russell These are the same thing that Cobalt Addiction sells, but a lot cheaper. CA is a rip-off if you ask me. No offense to them, but a lot of their prices are flat out HIGH!
