I removed the right hand sash balance for my Andersen Window installed in 1966 glass size is 40 by 24. I was able to identify the number better on the left hand sash balance that is still installed in the window JJ 12 31 95. Dimensions of sash balance are 6 1/4 x 2 7/8 x 3/4

I also need sash balances for similar windows installed in 1966 glass size 32 by 24 and glass size 32 by 16
