Unfortunately, there is no place to buy them brand new w/o the wheel. There are a couple options:
1.) Buy directly from Weber @ $11.95 each + $7 flat s/h.
2.) Try to find a CL deal with Weber wheels in perfect shape. Swap 'em & sell the CL grill for a profit.
3.) Have @zavod44 make a set of inserts outta whatever wood you desire. Then buy a matching handle & damper tab. Since you're OCD, you might as well get a matching set of bale rollers too.
