I cut a bunnch of the stock truck brackets off from 2 Dana 60s. You can heat and shrink the tube to move it. Neither one of mine moved the tubes more than .060" at the end. The one in the 64 has 300 passes, 60ft in the mid to high 1.20's@3350 The other in the high 1.30's@3775 Neither have bent. Both are over 45" wide with no braces.
