RedGreen,
If its not repairable, I have an idea for you. Have a good pumpkin here, 3.90 ratio, came out of my 58 with 110,000 miles. Good shape, no problems, but I replaced it with a pumpkin with a 3.38 already in place. Its in my garage, and free for the asking. You are in the general neighborhood (kinda), so come on by and pick it up if you wish.
