CZ7aPro coils/ CZ3D coils

I thought all of the CZ coils interchanged, except the early 4pins on the CZ5 or CZ6. I talked to Felix yesterday and he said, they would not. Maybe Dan or some other long time CZ user can chime in. Thanks Tom

All CZ coils are interchangable. The only exception is the 4-pin CZ-6 coils. (((The CZ-6a took care of this problem))).

As usual Tom is spot on with info..Indeed all 5 pin CZ coils from the CZ6A thru all the models right up to the CZ3D are interchangeable and that includes some of the very old ones that were white not black....

Thanks for the replies, I thought that was the case. I'm still trying to figure out why Felix told me the coils would not interchange.
