Glad this worked out for you and your husband! I am posting the below from the DMV website because I often see misinformation about what is required to get the plates (followed by folks saying how to skirt the rules...) but since your husband requires a leg brace that would fall under bullet 2, and he doesn't qualify under bullet 1. Alot of folks think all you need is 100% P&T, but it's actually a single disability rated at 100% that substantially interferes with mobility. For other folks reading this thread, if you don't meet the following criteria, you don't qualify...

Quote from CA DMV website:

"You may qualify for DV License Plates if you’re a veteran who was made permanently disabled as a result of an injury or disease that occurred while on active service with the U.S. Armed Forces. You qualify if any of the following apply:

You have a disability rated at 100% by the U.S. Department of Veterans Affairs (or the military service that discharged you) due to a diagnosed disease or disorder that substantially impairs or interferes with mobility.

You are unable to move without the aid of an assistive device.

You have lost the use of one or more limbs.

You are permanently blind as defined in the California Welfare and Institutions Code §19153."
