John, sounds like you're a purist like me! The correct original location
for this ground strap is across the front engine mount rubber. It literally
attaches to the stud of the mount on the engine side, and the bolt of the
same mount on the frame side. The idea is that, since this is a pivot point
it is the location of least movement, in contrast with a cable that runs
from the frame to another location on the engine that moves side to side.
You want to minimize the amount of movement this critical connection makes
to discourage the Prince of Darkness from visiting!

Also make sure to ground the steering rack or your horn won't work.... ask
me how I know! :-)
