I bought mine from eBay. Some sellers will take the spindles, shot peen them then they are outfitted with OEM hubs and OEM dust shields.
I am 99.9% sure this is the seller I went with when buying mine. Super fast shipping and pieces were in great condition.

What K member will you be running? That will decide what year spindles to use.
I will be going with the MM provides with the street & track kit. From what I remember you posting you said to use the 96+ years?
