VS1400.
The OEM humps cost me $400.00 including shipping, I don't know yet how hard they are to put on/off, as they haven't been delivered yet, I just bought them yesterday. They should be simple to put on and off as the factory version uses the spinlock system to attach, just like the hardtop. I found my set on the PCA mart classifieds at
http://www.pca.org I saw a factory set sell yesterday on ebay for about $600.00 plus shipping and that seems to be more the norm for a set of OEM. You can buy a set of aftermarket from a place called GT Motorsports for around $399.00 plus shipping unpainted. Take care,
Mike
