Need dimensions for ISCO III baseplate

Im starting to formulate some ideas in my head as to how to best attach the ISCOIII to the 11S1 lens wont be here till this week sometime hopefully but I need the dimensions of the baseplate that the ISCOIII sits on, length and width would be fine
thanks in advance

Thanks Mark im going to have to fashion a piece of aluminum and attach it to the pj mount somehow so the measurement comes in handy, do you have a pic of your setup with the ISCO? how do you have it mounted and are you using any kind of slide?

Cool let me know who you come up with, Cineslide will be released soon from what I understand, Im assuming the the slide for the UH380 cant be used?
