Narrative:

On vector base turn to ILS 36R mem at 2000 feet. I noticed autopilot was struggling. I suspected wake turbulence. I disconnected the autopilot when the aircraft was slow to respond in roll. It snapped right wing down to 45 degrees then back. We were in trail of a 767; which flew our approximate track previously. Spacing behind heavies is allowed to be too close in my opinion.suggestions: increase spacing between heavy and lighter aircraft.
