I think I have the wrong rubber mounts

No, the bracket is wider than the 340/360 mount. U can add a couple washers/shims to take up the slack or slice the mount and remove the amount needed then weld it back together. Some 318 brackets may need a short piece of flat iron with a hole for the bolt welded to it. Kim

Thanks! I may have a 318 mount laying around. I dug through my email and found the pics of the 340 mounts I bought. Guy said I e ear was welded but worked fine in his for years... Now, I'm thinking I was desperate and wanted to get the motor in. That was 2 years ago. Here are the pics he sent.
