I just tried ordering the MOOG k160062 and the MOOG k160043 spring isolators from Jegs. They have the K160043 so they are sending those. But they sent me an email stating the Manufacturer has discontinued the k160062.
I looked on ford parts.com and it appears they arent available from ford any longer either.
I finally found a low mileage 05 dana 60 4:10 axle so im gathering all of the remaining odds and ends so i can start this conversion in the next couple of weeks.
