Hey David: I"m afraid it"s a little of both. The outer tube has a slight swell along the weld line, so I had to grind a trough along the inner tube to loosen the fit. Now the problem seems to be the "T" is slightly off of perpendicular, just enough to cause a problem(combined w/ the close tolerence mentioned above). The "T" is made from 2" square tubing, may be difficult to adjust the angle. The slider moves in & out quite easily by hand, but I guess the inherent eccentric loads caused by the assembly geometry makes it "sticky". I may try to take a little more off the inner tube all around, see if I make any headway. I need to work a little more on the hook, too. I could find nothing even close to the original 1-piece casting. I used a piece of 1 1/2" square tubing w/ a 5-ton tow hook bolted inside. The tube is drilled for a clevis pin pivot & beveled @ the pivot end. Angle iron pieces, bolted up under the diffy, create the pivot bracket. The "hook" assembly fits right up between the brackets. It was a perfect fit on paper when I did my calculations, but very tight when I bolted it all up. Had to grind on the tube quite a bit to make it drop at all, but still needs more work. Jeff
