That's what I found out. The uppers are from an old VW Bettle and the lowers are stock. I ordered new lowers, but found out I can't use them for what I'm doing. I'm putting 400ex spindles and hubs on my 250. I should have ordered 400ex lower ball joints. The uppers that I ordered, I was sent left-handed threaded ball joints by mistake. Got 4 new ball joints and can't use a one of them lol.
