The classifieds forum is not the place to ask questions. Questions go into either the tech or talk sections. Opinion questions go into the talk forum, specifically.
Once you get the answer to your question, if you decide that you want to look for a set of seats, you would then post a want ad in the want section of the classifieds. Notice that it doesn't go into the FOR SALE sections because you're not selling anything. There is a Want To Buy (WTB) section for these kinds of posts.
Holler at me (private message) if you have any questions. You can also ask the moderators and old-timers that are here.
