Farrell, I'm going to crawl out on a long thin limb, because I think I remember your name when in a discussion about a Super-A. Here's the only pics I have of that process.
Here's my old clutch disc..
...and you can see the 'strap-like things' to which CNKS referred. This side of the disc faces to the rear. That is, the other side goes up against the flywheel.
And here's my old pressure plate...
I went into my clutch because my clutch was slipping badly on a downhill slope. You can see why. My pressure plate was warped, and only the shiny spots were making contact, maybe a shade less than half the surface. The darkened areas are grease/oil/crud, that I could scrape with my fingernail.
What I did was buy a new clutch disc, and a new pressure plate assembly, from IH. I thought maybe it was possible to get the old one 'turned', but decided against it, and as much for wanting to be sure I had new strong springs. It wasn't a good feeling, heading downhill, to have to be thinking about how I was going to 'ditch' off my tractor as it was heading toward the trees. LOL
IH took my old pressure plate assembly, but I can't remember if it was a 'core' thing, or if I took it just to compare, and they threw it away for me. Probably the latter.
Since I had gone to all the trouble of splitting the tractor, (and I'm not saying how long it took me, being my first time, and because Hugh will laugh at me, because he can split his and put it back together in an afternoon), I decided just to get 'new'-everything, including a new throwout bearing. My clutch disc still had a good amount of material on it, but for the cost, why not new? I thought- maybe the materials have gotten more advanced. Maybe not, maybe I got hosed.
But why put 'er all back together only to risk finding the old TO bearing going south in another week?
Here's a pick of my clutch put back together...
..and you can see those 'straps' peeking through toward the rear.
BTW, the new pressure plate from IH came with the clutch fingers already perfectly adjusted to height, and you can see the adjusting studs locked with some yellow stuff. All I had to do was bolt 'er on.
Also, you can see I put on a new ring gear (my old one was pretty bunged-up), and where I messed up. I didn't know there was a lip on the flyweel, and I broke a third of it off getting the old ring gear off, so I just ground off the rest of that lip. A rube mistake. Live and learn. (My best lessons have always been when I screwed up.)
Also BTW, couple of suggestions-
To avoid warping the new pressure plate, tighten those 6 bolts that hold it to the flywheel a little at a time, working your way all around.
Before you put your flywheel back on, think about a new pilot bushing in the end of the crank.
Also, if you get your flywheel refaced, have them do a 2-level facing like this...
...in which the surface on which the pressure plate sits stays the exact distance away from the surface on which the clutch disc sits. Maybe it's overkill, but that way there will be no reduction in designed-pressure of the plate upon the disc.
Any other questions, just fire away.
And if you're not talking about a Super-A, well then, um...never mind! LOL

Today's Featured Article - Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
