I'm looking at your yellow build (photo 5 of 30)... it is truly an awesome machine, and I could go on and on all night raving about it...the attention to detail and perfection is superb. I am almost ashamed to ask such a trivial question, but nearly everything is evident from the detailed photos...but where can I purchase one of those 'bobber seats and offset posts??' I told you it was trivial, and once again I apologize...but I have never seen one quite like it, and it is exactly what I need. Thank you. You can pm me here, or email pfk@naples.net.
