In order for our parts department to accurately provide you with replacement options, we are going to need to know more information.
Could you possibly provide us with more pictures of the tops and bottoms of the balances? There are many different options for top and bottom pieces on the balances, so knowing exactly what you have on your current balances will get us closer to an answer.
Also, there should be stamps on your current balances. These numbers will also help narrow down the possibilities.
