|  Hey Biff,
 
 Duke, Desi. Lee & Irene would ALL be better sources of info on this, but as I understand it, those are TOTALLY unattainable these days. But, yes, it sounds like you're describing tracker base plates.
 
 PEACE
 
           Jay....
 
 However, Irene, DOES have some hook-up for toe-stop attachments to go onto any plate you've got..........talk to Irene....
