Hello,

Unfortunately, our company does not carry replacement mullions or framing, which would be specific to the manufacturer. 

As for your lock and vent latch, take a look and compare the specifications of the 90-253 cover, 90-252 latch, and 90-260 vent latch to your original hardware. Thanks for posting!
