Hello ''HRO Experts''', Before I venture into it too deeply----I need some Coil Sets for an HRO-5.---Only have a ''JC'' Coil.-- I do have an HRO-7 with a full compliment of coils (A,B,C,D ) Can those be used in the HRO-5 and if so ,will I run into trouble with alignment and not be able to use then interchangeably ???
