Answer
Hello Troy,
I appologize for not answering the question sooner.
I was out of town, and signed out on vacation, but the All Experts system let me down, and didn't get my vacation posted.
In case you haven't gotten the answer yet, I don't know, because I made one with a grinder, and an old wrench.
Auto parts house may know, but could also measure a new hub for you.
