Replacement clutch on the cheap
...I found "kevlar" disc material to hold very well....with heat
From the looks of your pics of the McLeod disc it was organic material on one side (aka stock) and a composite puc type on the other (may have some kevlar in it??)
my ZOOM HP is Kevlar/Kevlar puc type on both sides.....and holds well running a tire in a 4200 lb car with 383...FWIW
