Question crank help please

i built a bike for a friend and before i was able to inform him properly he collected his bike from my garage and.....blew the motor by not mixing his gas properly.

long story short the main bearing seized up and it needed a new crank.

i ordered an 80cc/66cc crank from bikeberry however upon arrival i noticed it was slightly different from the one that came out of the bike.

the old crank is exactly like the one on bikeberrys website with the crank covers that screw on.

the new crank (that i ordered from bikeberry) does not look like this at all

my question is will it work or is this crank from a whole different style engine?

the weight of the new crank "feels" slightly lighter and "not as thick" by about an 8th inch other than that the rest of it fits perfectly.
