I ran into the same problem. All the local yards wouldn't pull the assembly for me and I had to eventually call the ford dealer. The dipstick tube was only $24 dollars and I bought a dipstick off ebay for $12 plus shipping. The the closest dipstick in stock was in lubbock texas. There were 2 other dipsticks on ebay, but that was 2 weeks ago. Try that and I think you'll get it.
