Harley wheel on stock front end

[lumbee]

Hey guys. I'm wanting to run a 21" HD wheel on my latest project and am looking for something that will fit between the stock lower legs. I'm thinking something 5-6" wide (bearing to bearing) is what I will need. I'm looking at these fore TC Bros:

Does anyone know if either of these will fit? I can handle the axle and spacers, I just need something that is narrow enough to fit between the lower legs.
