Hey I hope someone can help me. I’m exhausted all options available to me locally . I have a 1991 f250 Twd. I had to remove the drive shaft and and yolk to have it balanced. The flange nut
holding on the yolk is damaged . Ford parts manager said they do not
make the nut anymore try fastenal . Fastenal could not
order the part . Using calipers and a thread gauge we came to 7/8 - 18. I’m about 1200 dollars into a used rear end and returned driveshaft . All that is holding me back is this nut . For about a month now. If anyone has one? Any advice at all . Out of stock on every site and as I said ford couldn’t even help me. Last resort fill my drill hole with weld .
