any machine shop can do it. Just gotta take em and expalin wat you want done. Plus it'd most likely be cheaper than having someone else do it, cuz you wouldn't have to pay outrageous shipping fees.
just updating....got my spindles and axles back. john did a great job! axles looked really good. toy hubs slid right on the spindles with no spacing needed on the calipers. everything turned out great. 20s bolted right on.
