@pfbourassa I downloaded you file. That part is one solid piece up until it mates with the Hydralics where it “Forks” out into two tips. Take a loot at the Schematics link that Kent posted at the top for each part.
I found some similar bucket designs. I am willing to bet that they all share the same basic parts (manufacturing practice is to copy parts when possible)

Also here is a decent back-shot of the bucket we are most likely going to try to replicate (With Forklift Forks Included!)
