Ok, so I bought this '69 F-250 that is a conglomeration of parts. It originally had a 360 in it. Now it has a 300" 6. Stuff like that.
I just tore into the front end to replace the king pins & the set I got from the parts store are too small. OD of my king pin is 1.053". According to O'Reilly's website, Moog makes a kit for a F-350 that has a pin diameter of 1.054".
My question to the forum is this: Did the F-350 have different front end geometry?
When I picked up the truck, the front end had way too much camber. I may need to add spacers under the springs.
If common sense was really common, wouldn't everybody be using it?
So no hits in a couple of days? I guess I'll post a couple of pictures to see if I can jog somebodies memory.
This is the I beam. I noticed it had a bend where others I have seen in pictures here are straight.

Any help would be appreciated.

According to the Master Parts Catalog, those axles were used in '71 (From Serial Number M00,001) and '72 F250s with the 3.5M front axle capacity rating. (GVW for trucks using those axles was 7500# in '71 and 7500# or 8100# in '72.)
You can see from the following chart the various kingpin sizes available:
I'll bet you got the kingpins made for the trucks made BEFORE Serial Number M00,001, which were smaller.

I went to the parts store yesterday to get wheel bearings for an F-350 & they didn't fit. They were too small on the ID. Then I went to the NAPA store & the guy did the smart thing & ordered them based on bearing number. Pick those up tomorrow, since the NAPA store near me is closed on Sundays.
After a little research on the Internet last night going from what I measured, it looks like the these beams came from a mid 70's van, based on spindle diameter. The van also used the same size king pin. The inner bearing has an ID of 1.781" on my spindle & F-250 & F-350 use a bearing that is 1.625"on the ID.
This has been a hassle to get this figured out, but fun at the same time. I missed having something to work on that is not my daily driver.
A word of caution though. If you are temped to try this conversion; DON'T DO IT. The E-Series van has different front end geometry so they could get the floor lower. The I-beams have so much drop in them that you need a 2' longer spring (or spacers) to get the ride height close. But the springs are too far inboard & hit on the bracket for the bump stops.
I guess it's time to start searching for F-250 beams. If I can find a set with the larger king pins then I can swap all my new parts.
