Quick update, as I've been working too much and traveling lately:
I purchased new grates for the restoration. I opted for the
StanBroil on Amazon because of the the price $38 shipped and the companies reviews seemed solid. Today was the first day I had a chance to handle the grates, measure the surface area, grab the calibers and verify the bar spacing and circumference.
Crossbars: 7mm measured, spot on to the description.
Weight: 2255 Grams or 4.97 pounds per side. These are heavy, heavy duty feeling and the weight shows it.
Stainless Steel: Magent test only, there's almost no magnetic properties whatsoever, maybe the slightest draw.
I have not a single issue or complaint, the welds look great, the craftsmanship is spot on.
10/10. I'd say even if these were $50 shipped, id still feel like I got a great deal over the OE Weber.
