Sorry Andy, I couldn't answer sooner as I was in Alaska all last week. I never did find the part as a stand alone item. I just took some aluminum flat metal and made some brackets to hold the lamp in place. It works well and can't be seen unless you remove the bucket. I'm just NOT going to buy a whole new assembly just to get a $5 part. Good luck.

Thanks for the reply, Gator. I found a guy on ebay who is selling used H5 assemblies for cheap, so I may go that route.
