hey guys im replacing the headlights on my car 90 for escort GT. but i dont know where to buy the stock foglights for it. or know wich bulbs to use for the foglights

The stock foglights will probably have to come from the dealer or junk yard. I wouldn't even think of going to dealer on something like this though. No telling what they'd charge!

Go to Wal-Mart automotive section and they should have a little computer there that you can look up your bulb number on.
