1979 ford ltd landau 302 motor mounts

I had a 78 Fairmont with a 302 years ago. Later mounts were available, but the mounts I needed (similar to) yours were available only from Ford. The Plus side is that this was a rather safe mount that did not split and allow the engine to "roll" or "jump" when it failed. On top of that, the part that actually wears out is the rubber part that is on your frame. The bracket that mounts to the engine likely does not wear out, therefore, there is no replacement available

You can try the Lincoln and Continental Owner's Club, as the 80 Lincoln had migrated to the same chassis and there is collector interest in those cars. Someone may be parting one out. Also try Hemmings Motor News for someone parting out a car that uses the same style mounts. Another alternative is racing parts catalogue. Maybe racing mounts for a Fox body mustang may fit (I know that these are very different cars, but the cross members look somewhat similar.

Good luck. These are rather handsome cars, especially the 89 - 91s.
