When adding a back brace do you guys completely weld or skip weld it. Also do you weld the ends of the brace to the axle tubes?
Thanks

I welded the whole thing but I dont think you need too. On the ends I left enough material that I could fold it down on top of the bearing flange. I used 2X3 tubing EDIT Here is a pic

I am going to be ordering a brace soon myself, finally. I plan on sticth welding it all the way around but will be continuous when I'm done. Like doing a body panel..Who has the best fitting one? Mancini?
When you decide to quit, THAT is the moment when you would've succeeded..

Mine is continuously welded as well, it's made from 2x4 tube.

I dont know who offers the best, I made mine out of the 2X3, but if yours is a longer housing then you might be better off using the 2X4 stock like Crazy did, it leaves you enough material at the ends for a wall

I was told to not run a continuous bead as it could warp the tube and...weld it with the axles in.
If you stitch weld it(jumping all around) with 1" beads and cool it, its not a problem but after doing a few I really dont think its necessary for a full weld JMO

For a little more work I think its worth the time and effort to go out to and on to the bearing flange with the brace. I have seen where they bend at the outter edge of the spring mount. All you have to do is notch around the edge of the spring mount wall and drill the holes through the brace but it picks up alot of strength out at the ends.... JMO

I tied mine into the bearing flange, but just the edge. The diff that came out of the car wasn't quite as short, it wasn't backbraced, and it was easily identifiable as "BOW" shaped. Even from a distance... This is the new diff, I'm wondering if I should have brought the backbrace out even further? I dont know, it looks fairly short(the housing width) so it would deflex less. I went out on to the flange just short of the wall so I could weld there
