Hi...I need the same part...but I think what you have is not complete...here are some pics of what I have...the first on the left is the complete part I think the next on the left where your barrel adjuster screws in at the top the next pic confuses me because on the right the long bolt has snapped and been left inside but something is in there with it around it, on the left you can see where the other legs bolt screws in to the other end of the part the barrel adjuster screws in to same shot different angle .
However in the second pic above it looks like the threaded part has been rammed against the part you're looking for.
It may mean I need two of what you have....I hope only one...if so I was going to suggest going halves on a fork to get the bits....Ive read on here internals for manitou2 and 3 are super hard to get hold of....I also read someone put a spring in one leg and kept the elastomers in the other, I might resort to that, if I can
