I have one NOS mount for small blocks. It fits many years of small block, mostly from 59-72. It fits many different body styles including full size Canadian Pontiac, Beaumont and Acadian as well as the corresponding Chevy products. It also fits some years of Camaro.  If you are not sure it's right for your car, please do your homework or contact me with your application and I can see if it's correct for you. GM used to different mounts on small blocks in the 60's and early 70's that look similar but are NOT the same. These typically sell on ebay for around $100-$150 pair US dollars plus shipping. I am asking $50 Canadian plus actual mailing costs and will include a matching used mount to make a pair.

While this mount is NOS, I did mount it on an engine many years ago but never ran the engine, it was strictly a fitting I was doing. I don't have the box for it any more.

The last picture is of the used mount.

If you've ever bought aftermarket overseas junk mounts you'll understand the importance of using a GM mount!
