Using two OMC coils should work fine. Won’t
be a lot different than what’s in side there now.
Once you get past all the goop there should be
some wires going through the coils. Should be
more than enough and you won’t have to do
any filing. Thay can be as long or short as you
think they need to be.
I would suggest you cut off the plug wire
sockets so you can solder the plug wires on.
The coils “must” be facing the same direction
as in my example.
