I would keep the stock legs, triangle, 8" wheels (for resale value, if you ever decide to sell). Find a used or donor 22.5" OKC (Original Kettle Charcoal) grill with the standard leg height, triangle, and 6" wheels, change them
out. This would lower the height about 3 1/2". The newer OKC legs already has the hole for the snap in retainer clip. Then sell the lid and bowl (on craigslist, facebook marketplace, offerup, letgo, or even here on the
WKC "Member Sales & Trades," etc.), or just keep it to sell later. You can also inquire if any other WKC members here has an extra set of OKC legs, triangle, 6" wheels up for grabs on "Member Sales & Trades."
