Difference in Motorcraft ignition coils

[Ringmaster]

Does anyone know the difference between the DG-515 ignition coil and the DG-529 Ford # 2W4Z-12029-B ignition coil? I cannot find any reference to the 529 part number anywhere on the web and it is being sold as a LS coil. Thanks.

That is the replacing coil for the dg-515......the full number went from a "BD" to a "B".....cannot figure that one out either!!

OK so why can't I find the DG-529 number listed under any dealer or parts dealer's list on the web. Can't even google DG-529 and get a response. Or any reference to 529 turns into 515. Nobody stocks the 529 that I can see.
