When I made my 1st set of straps it was for my 40 and I was fortunate I had most of the original hardware. I used some old used strapping material that I had. I was missing a 1 of the rectangular loops. I search my shop and found some wire similar is size from an old deep freezer basket and bent it to shape. Then I cleaned it all up and painted it. It appears your missing 2 D rings. You might be able to find some similar wire and make them. I only mention this because the hardware I use for the new straps sets are heavier and doesn't match the stk stuff. All the material and hardware that I use is contained in this thread if you follow the links. I decided I will not use cloth strapping and I won't sew the ends of the long strap to a point like they did originally. In the 1st post in my ad, I referenced the nylon strap lengths that I use. I'm not going to clean your hardware, I'll sew straps on what you send me. I will be careful with it, but it may get a little scratch. If you send me your hardware it will be $25 plus $10 shipping. I'll contact you when it's ready to ship and you can pay then.
