The plates forward of the k member were made from some 1/8 - 3/16 sheet I had laying around getting rusty. The rear plates were cut from a partial 54-55.1 frame I had laying around. I used some construction paper to make templates for the overall shape.
The holes were cut with my cutting torch. I found a couple of lids to something in the garage and used then as templates. The holes were then smoothed with a grinding stone on the angle grinder. It did not take too long to get them done.
