The lucas system off the mini and other BMc/BL cars come with different sweeps gears of between 90 and 124 degrees like VW they are stamped but you can change it by moving the drive peg position. The peg is located on a dowel pin and spot welded so easy to remove then drill another location hole and re spot weld of fix. Moving in towards the centre rduces the sweep angle.
Some lucas motors have adjustable park switches for fine tuning the position
