The arrows point to the small corner than needs to be ground just a little to gain clearance for the wide snap ring. I just used a 4-1/2" grinder with a 1/8" thick metal cutting wheel and slowly made an approximate 0.030" deep cut and worked my way around the entire pressure plate. It is possible to install the snap ring without grinding the plate but makes the clutch pack a little tight which would cause it to drag a little in reverse, not a good idea for a daily driver that uses reverse regularly but running an unground/unmodified pressure plate hasn't been a problem for my drag race truck.
With increased line pressure, this pack seems to do fine with the stock (4) clutch count in 47re and 48re on diesel applications up to about 500 HP rear wheel horsepower, after that it's probably a good idea to upgrade this pack.
Note that you also have the older style return spring.
