Bob Bertaut 277 points ignition conversion

[Jack]

What the 277 points ignition looks like competed and to prolong points life I would suggest using the
Dyna points booster or Mr.Riggs trick posted on this forum somewhere.

1 and 2 and 1a and 2b are where the plate adjust. #3 was the old points hole that is tapped
4x70. #3b is drilled out to provide clearance on the back plate.

This is my points plate showing the critical hole location

you must grind the hole bigger on the bottom set of points(#1) for the new mounting screw, original size 4 x70
The bottom mounting screw head has been ground down thinner to mount the plate(#2). The screw is installed
part way and then the points mounting plate is installed . #3 is the other mounting screw.
