Window lock replacements

A home owner from San Pedro,California says:
I have Marshall windows that were installed in the early 90's.....quite a few have broken off and I want to replace them ASAP. The dealer I went through does not honor their " lifetime" warranty ,so I'm on my own! Don't really know what I'm doing,but was hoping for a little guidance from your knowledgable staff! I also have two front crank style windows and one of those locks broke. Could you please advise all parts I need to attempt fixing my windows. I appreciate your help very much! The measurements on the lift window locks (see,I don't even know the proper window names!) are 3 inches long by about 1 inch wide. The crank style lock is about 41/2inches long and 1 inch wide.

Thank you for posting. For the double hung window, please see our 90-005. For the casement window, see our 38-058L. Carefully compare this hardware to your owna nds ee how well they match up.
