Congrats on moving that rock, you deserve a week off!

Yeah, Painless made a custom wheel, apparently not realizing there was an existing one available they probably could have used.

There are a lot of similarities between SB (electronic, TBI and Maggie) and B/RB dizzys – even the old points type like Mr Yuck probably uses

The housing is the same but differs only in height.

The Maggie has flat ears for mounting the sensor, all the others use 2 screws that go thru the sides of the housing.

South of the insides of the housing the shafts are the same diameter and have the same drive tang. Inside the housing there are some differences between points and electronic, and between TBI and the Maggie, both in length and diameters. Another critical dimension is the overall shaft length. The upper diameter of a B/RB points dizzy is too small for the trigger wheel, so I need to disassemble an electronic version to measure it.
