Skip the red plates then, any will work with the rest of those parts, they do stop the bulk of the common shovel clutch problems. Everybody has their own favorites for this stuff, is what it is.

John Lee, hope I can jump in the a quick question(s) along the sam line.
What about using the original style 3-1/2 plates vs. the 4 and extra steel disc?
Rattle or non-rattle steel plates?

This lead to problems, the most common being they were to tight, clutch basket had to honed out to fit, I've seen several hubs and baskets ruined because of them, one all but welded itself together. Other issue, if they did barely fit they'd cause the basket to walk outward it would literally try to unscrew on the hub, back to dragging hard shifting. If things do fit correctly, in a wet primary they are ok. With a belt you'll be pulling it down regular and lubing them, you can not keep any grease in there don't care what anybody says, 50 miles it's dry and all the grease is now slung up into the plates.
Do what you want but they were one of those bright ideas that didn't work well in the real world.

The Big 52 as they were called back when was one of many aftermarket attempts at improving the shovel's notorious clutch issues, idea was with full contact long rollers the clutch basket would run true on the hub eliminating the floating wobble that caused dragging, hard shifting, finding neutral ect. Problem is not all the hubs or the basket are same diameter some are tight, some have a looser running tolerance and the long rollers weren't consistent either they tended to be a hair oversized witha micrometer check compared to OEM.
