Here's the solution I've come up with. 100% serviceable, no welding required. Drill the holes first to maintain the factory bracket position. I used my 8" bench grinder to remove most of the weld and a hacksaw for the small weld fillet left to remove the bottom bracket. To get it over the bar, the bushing has been cut with a single edge razor blade, with the cut positioned towards the back. I used 1/4" grade 8 black phosphate bolts and nuts found at Ace Hardware.
