I'll be moving into a new garage soon (yeah there is a house too ) and will have the space to get some work done on my truck FINALLY.

I was just wondering if anyone here had any clue if the front track width was the same between a 68 F100 and a 77 F150. I plan on swapping the front disks to the 68. I've read that you can swap the whole front I-beams, but if the 77 is wider I don't think I'll like that. I've also read that you can just swap the front hubs, but it is a bear to change out the kingpins. I suppose I should put new ones in anyway since I'll have it apart.

Anyway just wondering if anyone knew. I guess I could just measure, but what points do I measure from?

They should be the same,but I have no data to prove it. If you want to measure, just go from the center of the kingpin to the center of the pivot bushing. That will give you a good idea on the lengths. I don't think you have anything yo worry about. this should be a straight bolt in swap.

I've looked into this for my '66. The twin I-beam design is basically the same from from 1965 to 1979, but there are three different kingpins listed for these years. I've also heard that there was a minor axle change in 1975. Simply moving the pivot points will change the track width so don't worry about that.

Measure the length of your current axles from pivot to king pin and compare. The disc spindles will fit any '66-'79 axles with the right kingpin. I think the biggest difference in kingpins is the lock pin location.
