Wait a Minute. Gold and Silver C grills were not made until 2000. The grill you have pictured is a Genesis 1000LX. Do you need an LP manifold for that grill?
If you have a 1994 Genesis Grill, it is going to be a Genesis 1000 to 5000. The manifold from the grill in the picture should fit that.
Basically, we need to know exactly what grill you have now and what grill you are looking to grab a manifold from? Your naming is unclear.
