Installing a Quaife ATB Differential in the Salisbury 7HA-2 and found one odd ball bolt on the cover, 5/16-24 and the rest are 5/16-18. Thoughts? ![[Linked Image]](https://tm-img.com/images/2024/03/24/IMG_5983.md.jpeg)

5/16" x 18tpi is either UNC or Whitworth (BSW). Only a slight difference in thread angle and profile between the two. Could it be a damaged thread recut to take the courser?
5/16" x 24tpi is UNF.

5/16" x 18tpi is either UNC or Whitworth (BSW), probably the latter although only a slight difference in thread angle and profile. Understood, but why is the one different?

I'm guessing that one of the bolts was lost and, instead of finding a correct replacement, whoever did the work just rethreaded the one hole to fit a bolt that he had. The more I get into this car, the less things like this surprise me. I'm currently replacing the brake and clutch master cylinders and discovered that the bottom edge of the firewall is not connected to the crossmember...
