Is there a difference in the diameter of the spindle between those on a V8 or a I6 1967 Mustang?

Thanks for the responses. From what I have found, the I6 and the V8 '67 Mustangs have the exact same spindles. The problem that I am dealing with, and what others might have experienced, is that a later model spindle from maybe a '70 model are larger than the '67 stock spindles and can be used on the '67 with a modified outer tierod end.

I went to a wrecking yard yesterday and took a spindle, hub, drum,etc off of a 67 V8 just like mine. After installing everything, but using my old bearings, I found the old spindle nut was too small. I double checked to make sure the bearings fit correctly, they looked identical to the other ones, so i just used the bigger nut and finished up.
I'm baffled. Could it be just the end of the shaft and threads are bigger? If the whole thing is bigger, wouldn't my old bearings be too small? Is my tire gonna fall off someday?

Odd. Hollander Interchange states that 67-69 Mustang drum brake spindles are all the same. No differences for engine sizes.
I honestly don't know what you've run into. But if your bearings were the wrong sizes you'd either not be able to put them on or they would allow a very obvious amount of play/wobble. Are you positive the donor car was a 67 and not a 66 or something? That's about all I can think of, but on a 40 year old car a lot could have happened in that time. You can't trust them to have stayed completely original the entire time.

Well I used to have a 67 mustang with an I6 and its spindles were smaller than the spindles on my 67 with the V8....
Spindles from 67 were all the same, drum or disc, 6 or 8 cylinder.

I suspect that your car was either an early 67 originally fitted with 66 parts (It happened), or the spindles were replaced at some time.

I have a 67 Mustang that came with an I6 and when I believed that the spindles were different, I purchased a set of spindles from a V8 car. But in the time since, I learned that they're the same. And to prove this, I actually took the hub and everything off of my "I6" spindles and they perfectly fit the "V8" spindles, bearings and all. They are in fact the same.

The spindles for a 67 are the same for V8 and I6, but they are different for drum and disc brakes. The 66 spindles were different for V8 and I6. A 67 spindle will bolt to a 66 but you have to use the 67 outer tie rod. For a 67 you can use the spindle from a 71-73 but you have to use the outer tie rod and bearings for the 71-73. You can get them new from cjponyparts.com or hotrodsusa.com.
