This kit is just as awesome as I was hoping it would be. I only wish the packaging helped keep the little brass thingies separated. I accidentally installed one of the burner ones instead of the tube one.  This was obvious when I started seasoning the griddle because three tubes were on afterburner mode and one couldn’t get out of low gear. Anyway, it was just packaging. The instructions were great. Great product. Thanks. 
Oh, it might also be helpful to include some thread sealer in the kit.  Annoying to have to buy that separately *shrug*
