I'm opening myself up for a bunch of "wow is this guy stupid or what" but
let me give you the chance!! I have always been under the impression that
the position of the distributor drive gear wasn't all that critical as far
as the engine's performance was concerned, but rather on the older
air-cooled engines(and Vanagon 80-83) the placement of the offset on the
drive gear only mattered as to getting clearance for the vacuum advance unit
to turn without restriction against other engine components. As long as the
#1 firing notch on the rim of the distributor was aligned at the proper
angle to the offset of the drive gear(assuming there's space/clearance for
the vacuum advance unit to turn to set timing) when the engine is at TDC on
the #1 cylinder, does it really make any difference? Yes the wire harness
for the Hall sender may not reach if it were somewhere other than the
factory location, but fretting over exact placement seems like needless
stress to me.
I await your comments.
