I'm piecing together the ignition parts for my twin plug 2.8.

I've got both 0221121001 and 0221121006 ignition coils on the shelf. (still need to test).

I read that the 006 is for 74-76 only but wondering if the two of these are compatible enough to work together on a twin plug set up?

Anyone know what the difference between these 2 coils might be?

They will be used with classiretrofit CDI plus units and a locked converted twin plug distributor.

Thanks,

Jay
