I finally got ahold of someone at Vogelzang about the door.
They will sell just the door and frame for $65.00. The guy I talked to said it was still a better deal to by the kit but if i didn't need the legs or flue collar that it would make no sense for me to get the kit.
So for anyone who cares, call Vogelzang at 616 396-1911 to order just the door and frame.
I also checked locally here at a store that sells wood/coal stoves. He has fire brick that measures 7x9x1 1/2" for $1.60. He told me he doesn't care flue collars but told me to check with a local steel dealer for a short length of 6" pipe to weld to the drum for the flue collar. I will have to look into that.
