Hot Rods 40 dash with 32 tank?

I'm Building a new car and I have a poly 32 tank that excepts after market 5 hole sending units and I,m running a 40 dash with stock guages what sending unit do I need to get for it so the gas guage reads right?

 

I believe I have the sender you need. the sender itself has 6 holes but I have an adapter plate to fit on the 5 hole tank. Shoot me your addy and Ill send it to you. If it doesnt work send it back or send it on to someone who can use it.

 

your `40 ford fuel gauge needs a sender that has 73 oms empty and 10 ohms full , plus you will need a voltage drop if your using 12 volts

 

Thanks Guys,Mel
