Better gearing for my 7 1/4 SBP rear axle

Is there anyone out there that might have a sure grip and a 323 or 355 set up for a 7 1/4 rear end?
As far as I can tell, nobody is making 3.23's aftermarket(?) for whatever reason, but there are plenty of the 3.55,3.91,4.11, sets out there...partially thanks to the use
of the 7.25 in the frt of the Dakota 4x4 for a handful of years....... there are some OE sets out there..even new so check it out. Post in the wanted forum & go to the
mechanical parts for sale and the wheels/tires suspension for sale & use the search function.
