take 1 pickup out of a '76 distributor?

I have a '76 with a Holley and an MSD 6al, no transistor ignition unit. The distributor I have is the Federal model with 2 pickups, each with a signal wire, 1 red, one brown, and then both sharing a common green wire. I can't get a conclusive answer about how to hook this up to the MSD, so I'm wondering, is there any reason I couldn't take the extra pickup out of the dizzy? Then the directions for hook-up are clear. Is there a different advance, curve, or any other difference? Since the California model only had one pickup, I was just wondering.......

thanks
