When switching from a buick 231 to a Chevy 305 you need to switch the frame side mount pedestals as well, best bets would be out of a grand prix or monte Carlo that came with a Chevy 305, or, if your in Canada only a cutlass with Chevy 305.

You don't just use the buick frame side mounts on the crossmember and try to piece it together

These are the frame mounts I used when going from an Olds to a SBC in my Regal but I already had a used set of the upper clamshells for it.

There are aftermarket uppers available but for a 305 swap I would just look for some good used ones but verify the car they came from since there are different height versions.
