I am looking for the hole layout measurements (distance between screw holes on the base) on the colt plunge base. Can someone with a colt plunge base measure it for me? Thanks in advance.

Chris, the hole centers on mine are a rectangle. It looks like they were shooting for 76mm x 68mm They almost got it. :( center of spindle seems to be deliberately set 3mm off center on 68mm side.
