94 is wider trac width
a jeep axle will need tub work and get some wide rims.
the 10 bolt you have will do fine, add a suregrip and fresh bearings set up with a solid spacer not a crush sleave.
same for a 9 1/4 fresh pinion/carrier bearings and set it up with a solid spacer. fresh spider gear/washer kit with a new pin.
$$ well spent if you saty with stock 10/12 bolt rears.
myself I prefer the 8 3/4 in everything.
around here the 10/12 bolt stock axles are MIA/gone
I would like to find a 10 bolt 3.21 pegleg myself.
