The attached photos illustrate the tracks needing replacement. There are numbers on the track..2920 on two sets and 2930 on another.
Please give me any advice on what I should order. If additional measurements or photos are needed, please request...
Thanks,
Don

Hi Don, It looks like you have either our S351-30, with a 15-002 bottom attachment, or S390-30, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need to choose the spring tensions for your balances based on the 2920 and 2930 stamps on the original channels. Thank you!
