View Full Version : D1-4 backing plate interchangeability

10-18-2003, 10:38 PM
I have ordered a Bison plain back 6" chuck for my D1-4 mount and noted that Bison's backing plate was almost as much as the chuck ($98 versus $139 for the chuck). In a fit of parsimony I noted Travers selling PhaseII backing plates for D1-4 for $48 and wondered if anyone knows if they have similar BCD or not. The pix of the PhaseII plate shows a BCD apparently predrilled.
