once again I come to this site begging for help... thanks in advance.

'48 chevy 1/2 ton original - I want to add disk brakes and use my stock 16 wheels and add wide whitewall radials that look more or less stock-
I ordered a 6 lug conversion kit from brothers and was told it would work with a spacer on the lug nuts - then waited 6 weeks while it was on back order and when It finally arrived I called once again to confirm that it would work with stock wheels- this time I was told "No"...
I am a patient person but...
does anyone know a bolt on kit that does work with the stock wheels????
