Hydro trans mounts

Hey I recently purchased a set of Hasport B-series Hydro tranny mounts and it's missing the piece that's circled. Do I need this piece? How important is it?

That piece holds the factory cable for the clutch

So would I need that piece if I'm going to be using the hydro transmission?

Yes, the HASport kit doesn't call for you replacing your whole clutch system, it only replaces the hydraulic slave cylinder with an arm that is moved by the factory clutch cable.

Without the piece to hold the cable, it will not work.

I see, is there any way I can make a bracket to hold that cable? Or maybe Hasport will sell me just that bracket...
