Technical Old School Forged Ford Axle Drop

I’ve got a 55 F100.

Been planning to have my original forged axel dropped...

Toward that end I saved a good 55 F250 forged axel just in case it was a better candidate for a drop.

I know Sid’s a HAMB Member, maybe he’ll see this and have some feedback for me. Here’s my question for anyone who has experience with old school axel drops.;

1) Are king pins between the 53-56 F100 / F250 different sizes?

2) Does dropping and using an F250 axel in lieu of an F100 axel introduce any complications in a successful drop?

3) Is there any benefit to dropping an F250 axel instead of an F250 axel?

He has some outstanding Ford truck threads on here.

 

Or just ask him directly

I am fairly confident F-100 and F-250 are the same axle/spindles.
