I need someone that has a Ford parts book or CD that can look up 2wd axle beam part numbers. It would be for 81 F100/F150 2wd cast axle beams


I am trying to find if they made 2 different axle beams for the 2 different king pin sizes that the on line parts stores show.
Or if someone can tell me all pins are the same size between the 2 kits.


The 2 different size king pin kits look to be between power brakes (5x4.5 wheel) and non-power brakes (5x5 wheels) trucks. Weight does not seam to be why the size change as both my trucks have the same 4700 GVWR.
Most show power/non-power brakes but 1 site listed power/non-power steering?


I don't know why the 2 sizes listed other than brakes and trying to find if it is in the bushings or the pins. I need to mix-n-match parts to get the 5x5 spindles on the 5x4.5 axle beams.
I am hopping it is the bushings so I can get the right kit and get this front end back together.


Thanks for any help you can give.
Dave ----
