there has been cases where the winding of “modern” … coils was transferred over and it involved some work altering the laminates to fit the coil openning…. I do not remeber which ones could be rigged to accept the newer windings .
I think it was in the Outboarder magazine some time ago so if you access to od copies see if you can find the procedure.
of course if tons of used one are floating around that is your best bet .
