I've got a '48 GMC, ser. no. FC10223421. Should be a 1/2 ton, 100 series, with a 125 1/4" wheel base. The wheel base is right, but it's got the horizontally mounted lever action shocks front and rear, and my manual shows that only to be on 280 series and above, but 280 series and above don't have a 125 1/4" wheel base as an option. I gotta be looking at something wrong here. I need to know to get the right parts..I need new king pins and bushings. By the way, who's the best parts house? And the tech tip didn't work for removal. He must not have ever worked with Wisconsin rust. I had to pull the axle and press them out. Heat didn't work either.
