Are BBO and SBO shrouds the same? I need to know for a 260-455 A body swap. TIA

 

fwiw, 76 parts book shows same shroud for 260 and 350 Abody engines with AC or HD cooling, and 455.
B and C body w/ac , HD cool is the same as well...

 

Thanks, I should have mentioned A body in my original post. I am working on a 260 w/AC car so I should be good to go. Thank you. Coming from the Buick world Olds is much more interchangeable. I do not know how GM made money back then with nothing being interchangeable and changing things like trim every year.
