Rt800 crossover upgrade

Options
I have a set of mint RT800s I bought back in the day when they had just come out. I want to redo the caps and maybe replace the solid core coil.
Does anyone know what I should get for caps and resistor. There is a very old post using an 8.2 and 2.2 Clarity cap and a Mills 1.0 resistor. It is unclear how this turned out because the poster installed the 8.2 cap incorectly.
Any help would be greatly appreciated
