Lawrie, I read or saw somewhere that you can get a complete rear rebuild kit at a reasonable price that includes all bearings, races, seals, gaskets/shims, etc. I will try to track down that source. The last kit that I bought like this came from Joblot. I don't recall who's bearings they were including with their kit. May have been Timkin but probably were not made in the USA.
Now that I am back home for awhile, I will work on getting those items shipped, including the coils to Skip.
Cheers!!
ps....I am saving the original Ford script bearings from every rear I dismantle for possible future use. I believe they are much better quality than most new bearings being sold today. JMO
