b18ft volvo gearbox + 5 gt turbo clocks

Hello,
I am nearing the completion of my Phase 1 gt turbo with volvo 480 B18ft engine and box however i have come to a sticking point.
Is there a way of making the original gt turbo clocks work with the box? i.e. is the gt turbo gearbox sender unit compatible with the volvo box as essentially they are the same box?

many thanks.

The standard speedo sensor will fit into the Volvo box mate as they both are electronic speedo :agree:

Coolio i'd hoped they would be compatible but was unsure. cheers mark.

Fred, put some pics up of your project! Been a few months since we saw one of these conversions. :agree:
