Good morning, the window parts I am in dire need of are as follows: H8637MMX, holds the spring, measures 1 9/16-inch by a 1 5/8- inch, H8638MMX caps the spring holder, measures 1 1/4- inch in diameter by 9/16, I also need the springs for the previously mentioned components. They measure 1/2-inch wide; there are two of them per window. The only one I have access to right now is a broken one, the numbers on the spring are LA 406 500, which I believe is the longer of the two springs.
I need H8637MMX holds the spring

Hello,
We'd be happy to look into this for you but we would need to see clear photos an intact pivot shoe removed fromt he window, as well as the end of an intact coil spring that connects to the pivot shoe. The coils should have a stamp code that you'll need to choose the corresponding strength options. See the videos related on this page to assist you in the meantime. Thank you!
