Not good news, Dave.. Here is an OLD post that references the source I used to get a new aluminum one.. I don't know if they are still in that business or not..
I had the same problem on my Legend 37 September of 2007. The PO made a repair on the shifter tab with epoxy and glass, but it didn't stand the test of time. I purchased a new cast aluminum head that was machined perfectly. I picked it up from Constance Machine in Everett, WA. Phone number is 425-347-8920. It took some time to get it because he was waiting for a few more orders to come in so he could make the minimum pour.
