Tilt Latch for Alenco Single Hung

Question

I believe I found the correct replacement tilt latch for Alenco single hung window.  Please confirm that PN's 26-157 &  26-158 are for Alenco.  Second question;  Shipping is quoted as $8.45.  What is the maximum qty that can ship for that price?  I have several windows that need these parts.
Thanks...

The 26-157 & 26-158 are used by many window companies. We're not sure if Alenco used it.
