    Weld it solid if you're going to do it...I'd use 7014 or if you have a DC machine 7018.

    Do not weld it up like the article on the home page. Mine was done like that and it lasted for almost 2 years but the side gears were damaged (a few cracked teeth and one chipped off tooth) The hardened teeth on the side gears eventually cut into the welded area and create more and more play. With enough play the gears get hammered pretty hard.

    Set up one half of the carrier with the 4 spiders on the cross shaft and properl;y seated. Tack the spiders to the cross shaft lightly. Pull the tacked up assembly out and flip it over the other way, confirm the spiders and cross-shaft are fully seated and tack the other side of the spiders to the cross shaft. Trial fit the second half of the carrier with the tacked spiders installed and make sure it seats properly. If all is good pull it out and weld the spiders to the cross shaft really good.

    You might not.../forums/images/icons/smile.gif Welded the way I just described and you can still use the carrier to run a Detroit later. Welded according to the article and you may have problems earlier than I did...YMMV (Your Mileage May Vary)

    Got pics of that? Maybe even a little bit of a write up? I was thinking of welding the rear diff in my 12 bolt. But this makes me rethink how I want to do it.

    No pic's or write-up on that. I have a spare 14 bolt carrier i could use for an article but I'm not quite as confident in welded diff's as I used to be. Regardless welding a 12 bolt would be an entirely different procedure. IMHO a welded 12 bolt is a recipe for broken shafts...
