I hope someone can help me verify this engine coupler. The box it came in has a part #76850A 2. I need #76850A 2 for my Mercrusier/Alpha1 SBC305 1984 vintage engine but the one that was in the box is not the correct one.
Note the bolt pattern.
This is the old coupler I need to replace.
Can someone ID the new one and tell me which application it will apply to?
