Well you may be in luck. I have an old S2 race damper with the dual interruper rings on it. Unlike the stock press fit ring these have 4 mounting screws that hold them sandwiched onto the damper. The inner ring is the stock diameter, about 4.23" and the outer, one pulse ring is about 4.76" dia or so. Also have at least 4 of the corresponding dual element, 4 wire crank sensors with mounting bracket 
I plan to try and verify that the module works ok as t'bob proposes above.
And if anyone is looking, 3 of the billet v6 distributor lowers apparently like new, with I believe a built in VR cam sensor too
