need (20) 34" 3350 and (4) 25" 2440 with (6) top sash guides and 10 take out clips

question: the part number on the 2440 has an upside down A at the end and the letters B.S.I. (these letters are in the opposite direction of the part number)

the part number on the 3350 has an upside down G at the end and the letters B.S.I. (these letters are in the opposite direction of the part number)

Please see our Series 380 channel balance, 16-002 take out clip, and perhaps our 18-172 top sash guide. Carefully compare the dimensions we show for this top sash guide to your own to confirm if it can work.
