Are they high resistance or low resistance? worth checking before you grab them. If they are high, you can make them work with some wiring mods to the unit that fires them.I have some 1000cc rodchesters with a rail to suit?
The brand doesn't matter, its the size of the feed holes.Impedance isn't a problem, I will let you no see if there is something local but what rail is it I already have a sard
I'm still running 11mm I see map do 880 for $350 del so might go that way
