Window balance with top and bottom attachments

Question

Can you assist with tracking down the correct part number? I see its a 2420 but, need help with top and bottom. Thank you in advance.

Thanks for writing in. See either our S351-25 or S390-25. The only difference between these two balances is the 'depth' of the bottom nylon fitting, so compare both with me old hardware to see what matches best. You will need a stamp option of 2420.
