steel wheel question

[MidLifer]

I bought a Speedways disc brake upgrade kit from a board member for my 1950 3100. It has 5-lug rotors on it. I called Speedway and they do not sell 6-lug rotors that interchange with their kits.

I want to put on original-looking wheels and keep the original rear axle, and I'm wondering what my options are:

- Can I source 6-lug rotors that will work with this kit?
- Can I get identical-looking 5-bolt wheels for the front and 6-lugs for the rear?
- Do I need to have a machine shop re-drill the rotors?
- Or should/can I change out the rear drums to 5-bolt?

As always, the help and knowledge of the members of this board is much appreciated.
