63-66 engine mounts vs 67-up engine mounts

If you must, you can do a mickey-mouse retrofit of '67-'72 mounts shimmed with plywood to get the right total thickness. Best to keep this as a temporary get-by measure. If you buy the mass-market replacement mounts, be advised you are buying compressed cow poo from India or China and you will be doing the job again (and again and again and again) in short order. If you want to do the job once and never have to think about your motor mounts again, get these American-made ones.
