mallory 29026 to duraspark dizzy

I didn't find a direct answer, but this seems to indicate that you need a 29037 for the Duraspark:

Seems there is a direct answer in the Mallory catalog:
Points (single or dual) 29026A
Ford / Motorcraft, Duraspark, non-computer type, magnetic trigger 630
Ford / Motorcraft, Duraspark, amplifier trigger (except Ford TFI) 629, 630, 651M

The 29026 is for points ignitions only. The points are just used as a trigger and will last and stay in tune much longer. The only thing is you still have point bounce at high rpm (4000+) and there is still wear on the cam follower, so they still have to be set/checked and replaced as necessary once a year or so. Still better than a standard points ignition.
