I would call Will Smith and ask them about 8 lug wheels. They are very accommodating and could possibly drill the 17x5 1/2 Wheels with the lug pattern required.
I chatted with Wheelsmith, they don’t have a 17” 8 lug in less than a 7” width; nor will they drill an 8 lug pattern. I may have to go 16 x 6. I wanted to go with 17” for taller tires as I have a 4.57 rear end.
