I was checking a Cam sprocket off an '87 2.0L MM and darn if it don't match the '86 2.0L mm Cam sprocket. It looks like they updated from a metal pressed version to a metal cast version. I lined up the 2 and they seem to match, does anyone know for sure. I would like to use the '87 sprocket since the teeth appear to be a bit less worn.

The '87 cam sprocket is the 4 spoked, the '86 has the holes.
