Bought an 870 a few months back and did a deep clean on it last week and noticed a spring/ pin missing and the other was loose. On the Numrich schematic for the 870 it looks to be part 69 or 70, the trigger plate pin detent spring. Would any NS forum member be able to tell me which one from the pics? And if you have an extra laying around? I'm looking to replace the one pictured and put in a new one where I'm missing one. Parts are $7.50-$9 each on Numrich.
