the 4 3/4" lug stud pattern on their rear ends?

I was looking for a 12 bolt, 5 on 5 in the boneyard last week and found an open carrier rear end in a '78 Chevy c/10, however when I measure the lug studs on center, they were only 4 3/4". I was looking for a 5 on 5 lug bolt pattern to match my front end.

Thanks for any help
