iirc the older stoker single coil had a tighter gap then the dual coil which came out later and a dual coil will not fit well
also IF you are talking about the older stoker you will not be able to find recone parts unless you get very lucky.I've called recone companies,cerwin vega,all of the factory repair shops.the lady i talked with at CV even dug around for old numbers that were no longer in service.
the best thing would be to measure the gap on the sub and see for yourself
