I guess it's a bit more complicated with the V8.
Yes, the 300E is a straight-six.
The mounts themselves are quite cheap. All you have to do is put the jack under the oil pan, making sure to put a block of wood between the jack and the pan, and then only slightly (and very carefully) pump up the jack to just support the engine. After you unbolt the mount, carefully pump up the jack a little bit more so you can get the old mount out from under the mounting arm and slip the new one in place. The rest is in reverse order.
