Found 2 on ebay but BGF describes his as a slant and has a picture of a normal head lol. The other I have never heard of but has 1328 feedback with 98.2% positive. Neither offers combined shipping so I'd end up near $40 for the head and gaskets.
I just hope I can contact Zoom/Powerkingshop and they have and preferably give me a replacement without asking me to send the whole kit back. Now to go double check for cross threading even though I have always put the plug in by hand before snugging with a socket and never felt any resistance.
