There was a re-builadable coilhead for the Isub was listed on MVS site good while back looks similar to Zenith coilhead except the head itself unscrewed so one can recoil it or re cotton or both . Inquired if that coilhead no longer available would fit the Zentih and was told it will not.
Personally think they are a tad smaller that a zenith coilhead but do not have one to know for sure.
