I know what you are talking about but not sure at the moment what it is BUT if it stlii slides on ok put a dap od silicone over the remaining plastic clip to help hold it in the alt. Oh and so you know next time, the driva axel does not have to come out you just need to disconnect the tie rod and you would have room to get it out. I just got done doing the same to my car but I droped the y-pipe, easy as pie when you have air tools.
