my dillema

Did I miss something here? I don't see where the OP even mentioned a 383....

To the OP - can you have the bearing retainer opening enlarged to accept the 833 you have?

nope, i read about the 833 4 speed before i i had my first cup of coffee (im still only halfway through it) and i read 383

my bad...but its still a good idea to buy notch
