We unfortunately don't sell storm door retainers. The problem with these is that every manufacturer has a different design, and even the same manufacturer will change that design from door to door, year to year, etc. It makes it very hard for companies like us to keep up, so they're impractical to stock.
If you want this exact trim, I'd suggest contacting the original manufacturer directly and see if they can supply it to you directly. Otherwise, I do have an old fashioned trick up my sleeve that may work for you. What you'd do is take a few clips like our 70-180 and distribute them evenly around the frame using a screw like our 70-112. It takes a little more work, but they're very easy to deal with. That's how it was done back in the day and it still works on modern doors.
And you as well! Best of luck with the rest of the project.
