Yes but what you forget is that you are dealing with a older car that may have areas of rust not seen, moisture between panels etc. It's your choice of course but talk to a sparkie if you are unsure of what I am talking about as I'm no expert.

As you mentioned Petrolhead:The earth cable on your battery can you also run it up to your engine. It might cost a bit but it will help you out later when gremlins start to appear.
No Problems have surfaced yet PetrolHead and I've covered around 4500kms
I also have a Earth cable from my chassis rail to engine to bell housing mounting bolt.
You are right in what you are saying but I have a awfull lot of steel in my car and very, very little plastic.

A Sparkys tip,
Because our old cars are negative ground there is no reason why you cant earth the negative to the body at the rear. You must have a good conection clean and tight. You will also require a earth strap preferably the same size as the positive cable from your engine to the body. Your car uses the most current when starting and the starter motor current needs to travel back to the battery for it to work. Most problems arise when connections are loose or dirty. Late model engine computers also need a good supply and negative return to run correctly, you would be suprised how many people want to rewire everything when the problem is just a bad earth. Oh and another thing if you have a aluminium radiator it is wise to earth it to the body as well to eliminate any floating current that may cause electrolisis, very corrosive to aluminium.
