Here are some 16.5 x 6.0 6-lugs wheels I have. I believe they were also used on G10 vans as well; 3 nubs.
I read in the parts for sale section that another member stated they would fit disc brakes but I can't confirm that.
They have a 4" backspacing and I mounted them on the rear of my suburban just to see if they fit with a 9.5" wide tire and they do.
