Short answer is yes, they will work if the machine shop specifies .5mm overbore is enough.

Rods will need new bushes (to be honed by machine shop) to properly accept the new wrist pins.

and frankly I'd have the machine shop check the pistons pretty carefully if you plan on going with them. Ideally I'd find a set of MAHLE (oem) pistons (still available new in 1mm over).

Is that ebay price for one piston or six?
