Listen to Larry. Don't listen to anyone that thinks it's easy peasy. It's not. A quick search of the gasser forum will confirm it. Decide which fuel you want to use on the grill, then hopefully one the reabbers will be able to help you.LP and NG manifolds are different. Valves and orifices are different
Assuming, nobody on tvwbb.com can help you, keep an eye out for an old Genesis x000. I know the part nos. are different. I know the x000 is a 13 bar grill vs. your 5 bar grill. However, Weber.com says both the x000 and your grill take the same burner tube set. So the horizontal spacing and placement of the burners must be the same for both grills. Perhaps the only difference is vertically, allowing for 1 row of flavor bars vs 2 rows? So shorter-stemmed knobs might be required? If you see a beat up x000 for $20-30 it might be worth taking a chance if the manifold is in good shape.Thanks for the responses. I'm not looking to drill orifices - I can use either propane or NG - just need to find a readily available used manifold. Just need a donor grill now.
