Just noticed your a new comer as well.
Again, Welcome to 1130cc.com.
Best to send a PM as it gets their attention a little quicker.
You were first in and it never hurts to put in an offer.
Best idea is usually to put in your offer with the Private Message and then post a "PM Sent" in the thread to state your claim.
Best of luck to you as well, good deal on a K&N filter, looks like I'm too late.
