Strobe Slipper Fitment

[WheelMan]

Was lucky enough to find a (what seems to be) unused Strobe Slipper, but the pressure plates are for a 3906 Transmission shaft (the internal hex shape).



But I have a 3903 Trans, with the round shaft and pin drive setup.



Would I be correct in assuming I can use the rear 3903 pressure plate (with the pin drive) and metal slipper disc with the Strobe?



If so, I still face the issue of the front pressure plate. In images I've seen of Strobe Slippers (such as the one below), I keep seeing a part that I do not have, was not included with the Strobe I bought. I have everything except the part circled in red (which is basically the front pressure plate that sandwhiches the rubber spacer against the slipper).



Does anyone know where I can find one of these? Is this a part that is original to the Strobe?

I suppose I could probably make one, as a last resort.
