The post on the bbq rusted off and I am trying to locate a place that sells this particular model. It is an old model bbq but in excellent shape other than the post. Also I am looking for an owners manual for this unit.
Thanks in advance

Hi,
You may want to consider a machine/metalworking shop as an option. Most places sell valves, grates, burners, etc. You may want to try:
Broilmaster Gas Grill Mountings (http://www.hearthsidedistributors.com/Catalog/Broilmaster-Gas-Grill-Mountings/)
Manual unknown, sorry, not at the factory or Free owners manuals, user guides & how-to instructions | ManualsOnline (http://www.manualsonline.com/)
Peace,
Clarke
