Welcome to WAL. Glad to have you here but seems you missed a stop at the rules booth on your way in. No worries though, as I'm happy to provide a guided tour.
Here is the sticky for the For Sale forum that you skipped over:

Here is the Give us a Wave forum. Go here, introduce yourself, post up some pics of your rig.
http://wayalife.com/forumdisplay.php?11-Give-us-a-Wave
Then there's a whole bunch of sub-forums where you can participate, comment on other guys posts, answer questions, etc. Spend a few months there getting to know everyone.
Finally, once you feel settled in and know a few folks and are actively participating, we invite you to buy/sell your parts. You found the correct sub-forum to put them in, so no tutorial needed there.
If you take the time to do all that, you'll find you probably gained more than a buyer for your hood. You gained a community of friends and experts to join in the fun with.
