I now see the issue here.
The domed repro bushing matches the exterior dimensions as the original, so no issues there and can be used as is.
But the repro tabbed versions are not as wide as the originals, so they do not fit properly between the tabs and slide around.
Maybe get 2 sets of the tabbed bushings and use two per side! Cut them so they fit between the tabs. You won't see the parting line when installed. My .02
As to the suggestion about grinding the domes off, good idea, but since the domed repros are pretty much the same size as the repro tabbed ones, they too will slide around. (Sorry Lynn

)
One question, does anyone know when the change over in styles happened? I assume domed is early and tabbed is late?
