Hi, so I need some advice and technical knowledge from the gurus here please.

so I’ve fitted a dccd gearbox from a 2008 hatch into a 1996 v1 Impreza,
So the problem I have is this gearbox has no mechanical speed sensor, that my dash requires, also I have a map dccd controller fitted that used to control my 5 speed dccd and the map dccd, this also requires a speed sensor to operate correctly.
I don’t have an ABS ring fitted to my hubs as I have no ABS.
how would I go about getting a speedo into the car now?

Thanks
