    I'm not sure where you've looked, but if you provide more information, I'll bet we can come up with the manifold you need. First of all is it the manifold, riser, elbow or what that you need?

    Is it the 4 bolt flange like this?

    Is it the 6 bolt flange like this?

    Is it the log style like this? (probably not seeing as it's a Cobra drive)

    All of these manifolds are available. The 4 bolt is about $180, the 6 bolt about the same and the log style is about $100 more.

    Can you post pictures of the manifolds?

    They are all available. If you have a casting number it is easier. Otherwise, post a photo. I am in Wisconsin and can have them shipped directly to you.

    I'm in the same boat Gonzo and can ship from here, but I don't know what he has and the log style doesn't sound right on a Cobra installation. The 302 would have used a 4 or 6 bolt flange, not the log in 1989's, so I suspect something isn't right.

    I suspect the manifolds you want aren't OMC, but Mercruiser. At least according to the OSCO and GLM catologs this is what you have.
