What Tom says about lower plates being very flimsily is very true, however a few years ago Bratton's started making a very high quality lower plate with the correct thickness metal that fits properly, and if installed properly with the fiber washer on the condenser, will not short out. You can put a screwdriver in the hole where the cable goes and push very hard and nothing moves or shorts out. Got to give Bratton's a attaboy for making a quality part.
