Step back from the keyboard Brian !! Can't tell us you knew EVERYTHING about a Blaster first you laid eyes on it !!
Crank : left and right plus new seals. Counter balancer shaft. : left & right. Trans : 4 , plus seal. Clutch arm : 1 plus seal.
Hopefully you have a Clymers Repair manual or download PDF, most all answers are in there.
Highly recommend balancer bearing because they spin at same speed as crank. Inspect gear closely.
More than likely Ken O'CONNOR has what you need.
