Shop teacher needs help

Does anyone have a 1968-69 cam and followers? The one I thought we had is toast! if so let me know how much. check out the pics of the first day http://new.photos.yahoo.com/richdesimony/albums/
also what do you all think about the sl swing arm as opposed to the cb, on an sl.
The web site will be up soon, it's being built by one of the kids and we are getting free space from a local company so we can exceed the band with of the school server.
Thanks in advance
RichieD and the kids
