Tim--You can occasioanlly stumble across the official Ford tool kit for that hub on ebay.

I got one about a month ago for under $20.00

It's a suitcase full of pushers, pullers and adaptors.

One of these sets is with the guy who uses my P-Car. However, he is a bit on the stubborn side and swaps in the half shafts with pneumatic tools and the hub nut. I think he is likely to have problems.

Looks like you need more spares!
