Replacing Two Window Balancers

The balancers I am replacing have the following part number stamped on the back side: 25 4 FK Caldwell

The length of the metal frame is 26".
The width of the back side of the metal frame is 9/16". The width of the front side is 5/8".
The top guide appears to be your 19-002 and the bottom shoe(IMG_2288.jpeg)is 1 1/32" deep.
The clip on the balancer is pictured on IMG_2285
I will also
need the part number for the part pictured in IMG_2289; the part is 5/8" wide and 2 1/4" high. Thank you for your assistance!
