CP Pistons Question. not sure of size

[NJ3ndri]

I just bought a set of CP pistons 9:1 for my ka24de-t but im pretty sure the size was supposed to be around 89. these have 87-2a stamped on the bottom. isnt that too small? (87 is the size im assuming) and a friend gave me rods he said were for a ka. which i dont see anything but a number 32970 stamped on it. cant find anything on google. anyone with some info? it would be greatly appreciated . thanks

top of the piston measures 88.03 across. and 56.21 from the top to the bottom of the skirt. now im confused as shit . lol

you measure pistons on the skirt .75" from the bottom perpendicular to the pin

and you use a micrometer for actual size

for a .001 yes a micro but verniers will give him a ball park if its even 89mm pistons
