Am I missing something here:confused:

R/A:

"For installation in an automobile, an installation gasket set is required (in addition to the "internal" gasket set included in the overhaul kit). If your engine is for aviation or off road use, you may not need to order this gasket set."

And also from R/A:

"It includes the intake and exhaust manifold gaskets, the oil metering pump o-ring and the oil filter base o-ring. "

So basically, the R/A kit is made to go along with the R/A overhaul kit if you install your engine in an automobile. The other gasket set is all the gaskets used in a Mazda Rx-7 engine.
