Dash conversion ("favors" GNX dash)

[HellOnWheels]

Has anyone made or know anyone that made the dash conversion from the stock turbo Regal dash to the factory 78-88 Olds G-body "Ralley Pac" dash? The Olds unit has a tach, speedo, temp, oil, fuel, volts gauge, which somewhat favors the GNX dash?
Best I remember the wiring harness in the TR's are the same as in the Olds except there is no boost gauge on the Olds unit.

Thanks,
