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.
Remember the "TABS" are for only the lift on the torque and those mounts appear to give you a 1/4 inch lift, so not to break the mount. I never used these, but looking at your photos, it appears you may be able to face the tabs towards the motor or front and not face the headers, rear.
