Fuel pump measurements

I've come across some NOS fuel pumps over here, part# dont say me anything and the seller only know they are for Datsuns.

My car is more than a hour from me, so can one of you that have a spare, take some measurements for me, i like the distance from center to center of the mounting holes and also length of arm.

Thanks

Chris
