I may have a front D60 and rear D70 coming my way in the future. That would be totally uncharted waters for the ST, or Explorers, as far as I know. Depends on a couple situations, money included, but they're sitting at the barn right now. If my soon-to-be brother-in-law doesn't have the time to get them on his Jeep before starting med school, I may just take them off his hands. I'm not even sure how possible it would be, but the awesome factor would be off the charts. Those axles would be nearly indestructible under a ST. Not that I'm hoping he doesn't get them installed or anything...
Otherwise, I'll continue my search for a D44 and reading everyone else's projects until I feel confident enough to tackle this job. Oh, and I'll need a few thousand dollars. Please donate to my solid axle fund now.
