Hot Rods F1 or F100 brakes for Early Ford Spindles

yeah, I know - this topic has been around the block a million times........
but - my current project Model A roadster pickup (highboy) dropped I beam, been gathering up F1 brakes components for my front brakes.
a friend calls in, looking over my project and I'm telling him about my F1 front brakes and he comments " I think F100 (53-56) work much better and don't push the front wheels out so far".
question: is he right or are my F1 hubs going to be ok ??
help !!!

 

F-1 front hubs move the wheels about a 1/4" further out per side over F-100 hubs.
Nothing to worry about. Plus later model F- 150 rear drums can be used on F-1 hubs at a great cost savings.

 

awesome - thanks 42 Merc - I aint worried about a 1/4 of an inch on a fenderless car !! cheers

 

OK, so it's 7/16".

 

Measure the seal boss (where the seal rides), there are two different size seals. I believe it's either 1 1/2 or 1 9/16, I just put the F100 units on a '41 and it was the larger. I noticed that almost all the information out there states only one seal (the smaller one).

 

where the seal rides on the spindle is 1-9/16 on all `37-`48 spindles

as oldtimer said, a lot information recommends a seal that is 1-1/2....i use national part # 473441 that is 1-9/16

fyi......1-9/16 is 1.562

 

could you tell me what year of f150? thanks

 

Just ask for 1980 Bronco rear drums.

 

thanks rich!!!!

 

Thanks from me, too. I’ve stored that piece of info away for my future build as well.
