Does anyone know where I should go to have sfc's installed? There is this shop around here that is kinda expensive, but their add says "...Computerized Unibody and Frame Repair..." Would this be a place to go to? What kind of place am I looking for to do this? Any help would be great, thanks...

 

Computerized body and frame repair??
BS
Sounds like they're peddling a dumb gimmick.
Basically any shop with a welder can install SFCs. To save some extra money you can sand off any paint or junk from the mounting points and just have them weld it. Then put on something to cover the welds from rust. I would expect to pay $100 for a good job.
I would look for a body shop in your phone book. They'd definitely have a good welder. Specifically a collision repair shop, not a paint and body one, would be best. Ask them directly over the phone how much it would be to install sub frame connectors. You'll see some bozo's won't even know what they are, AVOID. I see about 2 dozen shops in my phone book that would qualify.
