can i use a piston of the same size from another kit

Hi about a month ago i ordered alot of parts off scooter attack, it was quite late so i forgot to order a few parts and only now realized i had forgotten to order a new piston. since shipping from scooter attack takes about a month i started looking at speedline and found a piston that might be viable for me, but i want to be certain.

my cylinder is the Airsal Racing 80cc, and the piston i need is this one, and the piston i can order is this.
these pistons are not for the same cylinder but it has the same displacement and are the same diameter.
if you know of any other sites that are in Europe that have fast shipping overseas please share it with me

Its risky, just because its the same displacement and bore does not mean the crown curvature (affecting combustion chamber) is the same nor the height of the piston pin to top of crown. Long shipping sucks, but its probably best just to go ahead and get the right one now.
