cluster redo

[76bonanza]

I am going to start buying my guages for my dash redo. I am going with autometer phantom guages mainly because I like white and they still have 3 3/8 availible. A few questions The gas guage is 0-90 ohms correct? And the speedo I would like to go mech for cost reasons how do I know if they will fit with our speedo calbe or will I need to purchase a new cable or adapter? Is there anything else about the speedo or any other guage I need to know? I am going with speedo and tach, water temp, oil pressure, volt, fuel level and vac.

Thanks for any tips.
