Front Spindle Question?

[Pbum5]

Can someone tell me what is a better/stronger spindle?

1967 V8 Drum Spindle or a 1968 Disc Spindle.

The reason I ask is I have swapped my 67 drums for 68 discs and removed my old 67 V8 drums for the swap.

If somewhere down the road I would like to upgrade to a 13” rotor like Mustang Steve Kit or Baers what is a better spindle to have for the larger disc swap?

If the 68-style disc is better then I will sell my 67 V8 spindles.
If not I will just hang on to them if I want to swap them later.

68 larger dia

the 68 disc brake spindles are larger I am told.

from 65-66 V8 spindles, and 67-69, all, spindles are all about the same strength as the spindles are the same size. in 1970 ford went to a larger spindle.
