Ohms for 1978 Fuel Sending Unit

I'm looking for an after-market fuel level gauge and can't seem to find the right ohm readings to match up the sending unit with the gauges... anyone know the empty-1/2-full ohm levels for the 1978 Blazer?

Just about all GM resistance based sensors of this vintage are 0-90 Ohms. Check THIS out.

Everything I've looked into suggests that things changed up in 78! The sending units are different starting with 1978... I'll look into the link...
