Blackchrome, Thanks for the picture. #4 is the sub housing assembly. I did purchase the correct one for my 1993. V4lu3s makes it sound so simple. A friend of mine said he thinks you have to align the pistons and valves at top dead center(TDC). Is this true? How is this done? Do any of the other parts in your picture need replacement when this distributor housing is replaced? All comments appreciated. Thank you.
