If you can believe it, I had a senior moment. My 78 came without a jack. I have been watching eBay and finally won one. I also bid on a hold down spring and won it. When I checked out my jack compartment, low and behold it had a hold down spring in it. So now I have two. I am willing to sell one of my hold down springs for what I have in it, $10.95 including shipping. The spring is in good shape; but could use some paint for the perfectionist.
