>>1865112To hopefully make my issue more clear: the cap is a 1" and slips inside the stem which is 1 1/8". If I use the above mentioned shim, the cap will only cover the shim and not the stem itself. If I use the shim upside-down, its flange will hold down the stem as well.
Or do I need to buy a 1 1/8" cap in this case?
