Both flys had the same lug arrangement and the same added cores for aux signals. Only the mounting plate holes were different, but who cares! Really, if a failed ctc16 or ctc20 can be saved by drilling s few holes and rearranging some pickoff coils I certainly would go for it.

Re-read your original (now edited....with the correction) statement - you stated it was used in the 16 TO 20, not true. 117426 may work with the 16.

As to the pinouts, significant differences between the two, with different pin 5, 7 and 8 - tire may be similar, with close resistance of the secondary winding, but the pinouts will have to be dealt with.
