It looks like you've got it all. It wouldn't hurt to change the coupler before you install the supercharger for peace of mind.I have an alternator relocation kit I'll sell. Brand new from ZZP. PM Me if interested.
Seller claimed he changed the coupler right before he sold it to me. I'll definitely private message you about the kit though.
