The "domes" can easily be ground off on a bench grinder with a coarse stone.
Assuming all else is correct (size) they should work fine with the fingered brackets.

Try these, at least the description sounds like they are correct for the tab/finger style:

I ordered these for a customer a week or so ago for his 69 Z,they are too small also.they will not work with the brackets with the side tabs.they are just like the ones I ordered through Napa, they even had same part number casting.

OK, thanks for pointing that out. Have you been able to find an alternative for your customer yet?

I have 6 of the ROUND Rubber Bushings that fit the 11/16 sway bar and the above clamps...

Wanting to determine value and who reproduces them ????
Mine have no embossed or printed codes/numbers

I also have the ORIGINAL 11/16 front sway from the #27 ZL-1

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?
