Your 71 is missing its large tube shield, that goes over the RF, 1st det., and IF tubes (left side of chassis when viewed from the rear).

Here are some pictures of my "Super" 71 which shows the shield you need:

Your next job is to find a replacement shield. I think Dick Oliver may be able to make one? Worth a try:

Edit: Sorry to hear about your knee and I hope you have recovered from that. I tore a meniscus in my right knee 10 years ago, no fun at all and it took awhile to recover. Arthroscopy had to be performed.
