Is there a difference between 360 truck motor mount and 360 car motor mount

The tread I'm referring to had to do with spool mounts. I remember an image of a truck mount on the pass side with some washers to take up the extra space and then a modified driver's side mount. However I don't think the person posting those images was the OP of said thread, just someone responding to another member so that's why it's so hard to find.
