I highly recommend one of our participating vendors on this forum, socalmotorsports.com
I've purchased a few things from John Dechane there (714.724.7978) and have received excellent customer service. He follows up with his customers, is really handy with special price discount coupons
and is more than willing to help if you have any questions whatsoever on products and technical details.
Give them a try! You won't be disappointed.
