They don't look bad in the pic; just surface rust to clean up on a bench grinder with a wire wheel if anything. I don't know where you would get new. It looks like the new sleeves are shorter and the washers fit over the ends so everything stacks up to the same height. The ends do not need to tuck into the sleeve. It would clamp through the sleeve and washers.
Yeah, those are the ones I could save, the rest had cracks in them or broke around the center when I pried them off the old bushings. That’s not counting the ones I bent the heck out of.
I saw that the MOOG K7103 offset kit has new slide caps so I asked MOOG if I could just get the caps. It’s a long shot but my other option is to pry them off my other car that is in a different stage of restoration. I’ll not be putting poly on that car so new bushings will come with caps. I would prefer not doing that because it’s not easily accessible.
