Single Brake Master to Dual Reservoir on ’66 Imp w/Auto Pilot Cruise

Getting the parts together to upgrade the brakes on my '66 Imp and thought this would be a good time to swap out the master cylinder. However, since the car has the Auto Pilot cruise control unit nearby, it looks tight, at best. I don't have the dimensions of a dual reservoir handy to check measurements.

Wondering if anyone else has done this and, if so, was it a 'drop in' replacement? I thought I read that some of the 66 Imps had front disc brakes, must've still used a single reservoir?...
