What is the correct front Spindle?

[Chief Brody]

What is the correct front hub spindle for the 1974 Blazer.

I am seeing "big bearing spindle" and "small bearing spindle" on eBay...I am not sure which one is right.
I have a parts illustration book but it doesn't give part numbers

Small bearing

Iirc, the big bearing version is for 3/4 ton D44's and 10 bolts.

so the ones that say "small bearing for drum conversion" is the right one?

Small bearing is the First Design series from early '76 and older. The Second Design started in '77 with all the little changes to axles, steering, etc.

Both types of spindles can be interchanged to the opposite years. The deal here is to use the correct bearing hubs to fit the spindles.

'76 and older 3/4 tons are all external bearing hubs whereas the '77 and newer stuff are all internal bearing hubs.

1975 and older Fords with the drum brakes ran spindles exactly like the GM line ran since the parts were made by Spicer. Ford started disc brakes full time in '76 and their spindles changed from 6 bolt to 5.

This is the only way I can explain the difference between the two spindles:

Here is a pic of the Ford spindle from '76 on up:

So does that mean the eBay one I showed will work or not?
