Merc 420 piston and rings
 

Im looking for a single piston and rings for an 88 merc 420. These are the 420 b/w trs combo. I just need one to get me by for the rest of the season. These are forged dome pistons with a single valve relief, stock bore, 4.25". The number on top of the piston is 3999295. I figure someone has some stock stuff left over from a build.
Let me know what you have.
Thanks
Chris
