early A body engine swap

Another thing I noticed is that it looks the design of the 2710 mounts have changed. I found some old forum posts and pictures about Anchor 2710 mounts, and they seem to have the locking tabs also encased with the rubber:

But every picture of 2710 mounts I found for sale, have the tabs separated:

That old design might be really good for my application, but I just simply cannot find them anywhere.
