 Ah, yes he did. However I was referring to the axle that is in the car now. I should have made that clear.

So in that case, if it were me, I'd be looking for a Ford 9" Traction-Lok with a 3.50:1 ratio or at least a 3.25:1. 429/460 are gas hogs, so I wouldn't want the revs up too high on the highway.
 Just my thoughts on that.

The old seal and bearing should have a part # on them.

No dice on the tag. I don't have a deepwell socket but it looked like one would fit if I tried it. The whole underside of the vehicle was painted black (yeah I know its a cardinal sin to buy one thats been painted like that to hide rust, but the rust looked/looks quite minor. Couldn't get a good picture of the hogs head.

Honestly, that would be to smart for me to take them out and just look at the part number.... Lol

I guess part of the idea was to know what to buy before I took it apart because I'm afraid of getting it too far apart where I can't even get it properly towed if need be. Is there a part number on the outside of the bearing so I could just take the axle out again and look and the seal should probably match or come as a set?

It does drink gas about like I drink beer lol, somewhere between 8 and 14 mpg, leaning closer to the 8.

 That sounds about right. I have a friend with a 73 Torino with a transplanted 429 and it does about 10 mile per IMPERIAL gallon, so 8 US mpg sounds about right. That's why I don't have a 429/460. It's bad enough with a 351 4V.

It sounds more and more like it's an 8", so will take the small bearing. If you used a 9/16" socket to remove the backing plate/bearing retainer that makes it pretty certain, along with the tapered axle housing tubes.

Only the high performance cars (427s, 429CJ, 428CJ,Bosses etc), including Galaxies, came with the 31 spline axles and large bearings.

Thanks. I just saw another video that had an early 8" and it looks exactly like mine.

I guess the next question is, is there any concern that the 8" won't hold up to the 429/460 power output or should it be ok?

Depends how easy you are on it. Ford had a reason for using 9" on all 351 and up.
