Hey there! I recommend our S351-29 or S390-29 with the 2820 strength option, depending on the depth of the bottom fitting. Measure as shown in the image below to determine the best match. As for the top sash guide, see if the specifications of our 18-199 align with your old one. Comparison of the S351 and S390 balance shoes.
