I've heard too many different stories from too many different people that now I'm confused, and really would like some credible info from someone.
I need to find out if the kingpin used in the Twin I-beam suspension by Ford in their 1/2-ton, 3/4-ton and 1-ton trucks from '65-'79 all used the same kingpin. The main thing I'm looking for is the actual kingpin diameter for each of these applications. I can't find this info anywhere, and I've been looking for some time. The dealership won't help, the parts stores simply tell me that there is one part number used for '68-'74 parts and a different part number for '75-'79, but that's all they can tell me.
Can some kind soul PLEASE help me wade through all this information (and mis-information) and provide the specs? Thanks!!!
