64 V8 A Body Motor Mounts

Hello,
I'm trying this for the first time so bear with me. I'm getting a bit desperate for what I thought would be an easy find. I have a 64 Dart GT convertible with a V8 (Its a newer 318 but the car did come with a 273 V8) and a 4 speed. I'm looking for engine and transmission mounts and all I can find is slant 6 applications. Anyone have a good lead for me? Thanks
