I like the bronze one that presses into the converter register.There is a Mopar part number in the archives.The roller unit may provide less friction but that is just one more moving part on the engine.Think of it this way,If you don't get the tranny PERFECTLY lined up you risk damaging those small rollers in a plastic cage VS a solid bushing that is far more forgiving
