What does this mean?   When Chrysler built our engines they built them with tight (exacting) tolerances (in terms of "piston to wall" clearances).  When ordering new pistons for your engine you'll need to know which size you need.  Chrysler listed the piston bore size on back of each block, however after all these years (and the number of times your engine has been cleaned off with Brake Cleaner, or if your block is caked with grease, etc.. these letters may no longer be legible.  In that case you'd have to remove the head and mic the bores in order to know for sure.   
 
In any case, if you are looking for stock OE Factory Mopar 2.2 Turbo Pistons, here's one of your last chances to purchase some.  Pistons are sold 2 per box.   ****PRICE IS FOR 2 Pistons*** as they come 2 per box.   When you order them, make sure you tell us which size you want in the notes.    Again, WE ONLY HAVE 6 pistons in size D and 2 in size B at this time.     Also note:  If you are honing your cylinders (I sure hope you are) and your car happens to have an A, B, or C size piston currently in any given bore (hole) you can simply spend a bit more time honing out that cylinder and install a size D piston in it - as the size D is the largest nominal size Chrysler offered/used.    If you need a piston larger than a D, then you need to bore your block for oversized pistons.    That's why the size D pistons are the most desirable when you are rebuilding your 2.2 engine.     Again, this price is for TWO pistons.  Order as many as you need but do not exceed the quantities I mentioned above, or we will have to refund you the overage.   
 
If you need 4 pistons....order  Qty TWO  (i.e.  2 + 2 = 4) and then you will receive 4 pistons with pins.
