7 1/4 axle needed

[64X2]

I am looking for a 7 1/4 axle for my more door 64 Valiant, it currently has a 3:23 geared 7 1/4, with a nasty growl to boot. I need to find a axle with the same ratio or better, I don't want to put 2:76 ratio in the car and lose the grunt that the car has. We load the car down and use it to go camping and with all that weight it needs the gearing.....also needs to be near Louisville, Kentucky so I can drive to pick it up.......
Thanks in Advance

I'd start by checking the axel bearings and go from there,I have several of those rears I saved for parts but none with 3:23's
