I did mine last week in about an hour. First, remove bolt through old bushing and push long support arm out of way. I cut the old bushing with a small
Stanley hacksaw, one of the ones for small spaces -looks like a knife, not the big rectangular style. It took about 5 minutes to cut the bushing since it is plastic and you only need to make one cut. After that, the bushing can be pushed out by hand or a couple of taps with hammer and screw driver. Installation of new factory one-piece style took a little longer, but not much after I sorted out some hardware. I used a 3 inch bolt (3/8") with a large washer and a 1" pipe flange on each side, with a nut on end. The 1" pipe flange (from Home Depot, about $1.60) is really a flat metal disk about 3 inches across with a 1" hole in center for a pipe, just right to clear the center bushing of the new piece and overlap the sides of bracket. Assemble starting with bolt, washer larger than hole in flange, pipe flange, new bushing, old bracket, flange on far side of old bracket, next washer, then bolt. Add a little grease and start tightening nut on bolt. It may start to go in slightly crooked, but mine straightened out as it went in. At end, the far side of new bushing is just flush with old bracket side, versus extending about 1/8" as factory did it. I left it there and swung long arm from firewall back in place, added it's bole through new bushing and done.
