I guess, I could wait and do an unboxing, install and review video on Youtube but, I'm no Youtuber so, why start now?
Anyway, I called my local Authorized KJ dealer on Monday and inquired about a replacement Wire Mesh Fiberglass Gasket for an original, pre-2017 Big Joe (Model #BJ24RH). He then called KJ for me (KJ simply referred me to the dealer), I was given the part number #BJ-MGA24 and told that they would in fact be able to order it from KJ. He called again yesterday to say that it will be here in a about week and cost around $90. YES!!!
