I've seen numerous aftermarket IFS with UCA mounts, Speedway Motors, Art Morrison,etc. None are bolt in conversions and a major hurdle with these assemblies is their designed track width vs frame width. Because our Mopars have unique wider frame width, the designed track width of the aftermarket IFS would leave your wheel / tires sticking outside of your fenders.
IMO...for ease, value and cost, I would repair your UCA mount even if i had to replace the entire frame rail assembly. Good used ones are out there.
