It was not so much asking the wrong questions in a sense. It was the repeated asking of the same questions in multiple threads. Most everyone here is willing to help out without blinking an eye, but when the same things are asked over and over again it can become slightly irritating or overwhelming to people. We were all new at one point or another and had to go through the same situations, I'm sure no one was offended by it, we are just trying to help you out before things went south and someone might have said something they would have regretted.
The best advice anyone can give is to use the search button at the top of the forum. Once you do this just read and read and look and research and keep doing so and you'll find more than enough info on what your looking for.

Use this to try and find answers, you may not succeed on the first attempt, just try to word it differently and search again, most question you will have, are most likely answered somewhere on here because they have already been asked by others. If you can't find anything don't hesitate to post up after looking and we'll be sure to lend a hand.
The next piece of advice would be patience. It is key to helping you enjoy this hobby and board. Not all members check in everyday but most will get back to you in a timely matter once they see the questions. Most vendors that supply parts have an area in the vendors section where you can get in touch with them about parts, pricing, availability, etc. just send them a PM (private message) and they will respond as soon as possible.
I hope your able to enjoy building and the forum, if you still need help finding something after searching or if your coming up empty, shoot me a pm and ill try to point you in the right direction. Don't let this set you back, just do a bit of reading and searching and I'm sure you will see this is the best forum out there for trucks and construction equip.
