Someone asked me if he could use my '72 front spindles and hubs on his '65.

I think they interchange but I've never done it.

Yeah. I put it bassackwards in the title.
Doktor says no more cappuccino...

 

Are both F100 4X2? F250?

 

Both are 2x4 and drums on F-100s.
It's been a long time since I was under a 65 but I think that they were almost the same Twin I-beams as the 67-72.
If the Kingpin diameter is the same and the height/length of the axle Kingpin housing is the same then I would think that this would work.

 

Ford only furnished the hubs with the brake drums. 1965/67 F100's used different sized brakes than 1968/72 F100's.

C6TZ-1102-B .. Hub & Drum - Use with 11" x 2" front brakes / Obsolete = 1964/67 F100 2WD

C8TZ-1102-E .. Hub & Drum - Use with 11" x 3" front brakes / Obsolete = 1968/72 F100 2WD
