The original BBQ's Galore went bankrupt, but was bought by new owners, who still operate it as BBQ's Galore. However, they did buy any of the older company's parts supply. However, all you need are the burner orifices for each burner (including the rear burner) and a Hose/Regulator Assembly to connect the grill to the grill tank. Follow the conversion instructions in the Owner's Manual (see link below) and you should be able to do it.http://www.grill-repair.com/images/grill/turbosts.pdf
I suspect if you call BBQ's Customer Support
800-752-3085. They can provide the orifices, as they are universal in fit. The Hose/Regulator Assembly can be purchased from any hardware store or home improvement center that sells grills and accessories, for about $30.00.
Once converted, you will see marked improvement in the heating capacity of Propane Gas, as opposed to Natural Gas. The grill will preheat faster and maintain higher temperatures longer.
I hope this helped you, Bradley and thanks for choosing FixYa. Happy Grilling!!
