Hello,
I believe these are the S351 series, but of course need to be certain. I know I need to replace both sides but should I replace these for the upper sash as well or just lube them with some lithium ? I need multiple replacements in 28 and 16 inch lengths, at least, and want to order all I need at once. Many Thanks and I look forward to hearing from you.
VRY,
Jeff B.

The Series 351 is defined by the combination of top and bottom nylon fittings, in size and style. In terms of style, your fittings match the Series 351. You have to check the dimensions on our site to ensure that they're the same size, though. The Series 351 comes with a 19-005 top and 15-002 bottom. As long as they match up then you should be good to go.
We always recommend replacing both balances on a single sash at the same time. You may not have to replace the balances on your top sash, though. It depends on if they're broken or not. That's ultimately up to you.
