Welcome, You will find a plethora of information here. I few observations that might help, Do a search before asking a question as more than likely its been asked and answered many times before. Some members are very matter of fact, not mean just straight shooters they are not Willy Wonka they don't sugar coat shit! I see you profile says 94 Ford Explorer, if that the case keep in mind this is centered on 20-25 Explorer ST with some PIU (Police Interceptor Utility) sprinkled in. If you looking to buy a ST this is an amazing resource to help you decide if this is the platform for you and what to expect along the way.
I hope you find your time here Informative and at times entertaining!
