thanks guys!
i tried calling a couple of local shops and they all seemed around 500$, my dad is stubborn though and went with sears anyway (what would i know about cars?! grumble grumble! lol!), their final total was 645$ still seems fishy to me, so i won't be going there for my 'stang thats for sure!
thankyou very much though cadreamin and maroon!
