In CT? Where?
I still go to S-K Speed on Long Island if I'm in the area. I used to live 25 minutes from it, I miss having it close by. They've been around since the mid '60s. They still have a performance machine shop associated with the store, they'll fill your nitrous bottle, have any AN fitting or ARP fastener you would ever want, books, exhaust tubing, turbo parts, fluids, tires, anything and everything. If they don't have it they can get it for you. The kids behind the counter are generally OK, a few have been there for a while now. The manager has been there forever, he knows his stuff.
