I have a 5.7 L with VP manifolds/risers and need a replacement manifold rubber end cap. I'm not sure if it's 1" or 1.25". What size and/or part number? Where can I get it the fastest? Is it something a local brick and mortar might have, or should I figure on getting it on line? Thank you.

I have heard conflicting reasons on why the manifolds are designed to need these rubber caps. One of them developed a split, and although the leak is small at this point, I do not want to run it this way, but want to get back out asap.
