HRE 15" waffles on 16" HRE's..will they fit?

[Shocktech102]

I need to know if the waffles and hex caps from a set of 15" HRE 501's will fit on my 16" 501's. In almost 2 months of searching I finally found some but they're 15"..I already asked HRE and they said they cannot confirm it as they don't make the wheels/waffles anymore.(Don't go to them with questions, they've done nothing for me. They originally told me the caps for HRE 505's were the caps I needed lol.) So does anyone know if these 15" waffles will fit on my wheels?

Thanks,
Matt
