Charlie,  

Everything moves, so my recommendation is to design to allow for movement.  Initially, I had my oil cooler attached to the re-drive adapter plate with bolts and rubber grommets.  The grommets took a beating as did the bolts and flanges.  A year ago I re-designed the whole oil cooler assembly and isolated it from the engine by securing it to the motor mount.  This approach has worked much better and I plan on keeping it as is.
