I bought some of these off Amazon.

Folding Shelf Brackets - Heavy Duty Metal Collapsible Shelf Bracket for Bench Table, Shelf Hinge Wall Mounted Space Saving DIY Bracket, Max Load: 150 lb 2 PCS (12 Inch, Black) https://www.amazon.com/dp/B07KX3TRYL/ref=cm_sw_r_cp_api_glt_fabc_Q6HTCJW9AJJ3N962RC52?_encoding=UTF8&psc=1

There are holes in the side of the grill. They didn't match the holes in the bracket so I drilled into the brackets. Added a wood shelf that folds down and the cover still fit over it!! Unfortunately I sold said grill and dont have any pics. Sorry! It did work well
