let me see if I can obtain a part number. When I replace them I do one side at a time, remove a tire, remove a bushing cap, jack up the mast rail, use a come along to pull the mast forward, slide the old bushing off, slide a new bushing on, release the come along tension, lower the jack, install the cap, and reinstall the tire, it takes about 20 minutes per side this way.
