As I noted in an earlier thread, I cleaned up my Silver B to make it look nice again. I know others were posting about replacing grates and I will say I love this new stainless rod grate that was on Amazon for 37 bucks. Not magnetic, good quality, and my first stainless rods ever. I originally had the porcelain steel from buying the grill then had replaced those with the porcelain cast iron as an "upgrade" when the originals were dying. Those porcelain cast iron were looking really crappy recently. I love the stainless look, it is way easier to clean, it still goes great grill marks as shown here (I thought cast iron was needed for those) and I haven't had any issues with spacing or things falling through. These are 7mm rods. I'm sure 9mm is "better" but IMO for this price I think the 7mm is a way better value vs spending 100 bucks for 9mm especially for an older grill like this.
