Twistgrip's 69 F3 340 GTS Resto

Aftermarket intakes like that Edelbrock almost always have two places to screw in sending units. What happened to those?
The sending unit is 1/2”, I am giving this a shot first. If I decide it doesn’t work or I’m not happy with it I will have to unbolt the intake and cut and thread the extra factory supplied location to accept the larger sending unit.
