Cast Crank main journal width… are these the proper bearings?

Hey guys. I found this one post and I want to verify that I have the proper bearings for my slant six with a cast crank (1977).

i found this post here on the forums giving me the sizes for the bearings. And I’ll attach an image of me holding my bearings to a tape measure. I know that’s not the proper tool for measurements this fine, but it’s what I got. It comes in under an inch, so is this proper?
