My aluminum plate is 0.5" thick; you can see it is routed around the rubber mounts, the center is wide open - just a 2.5"-3"" strip of metal left around the oil pan bolts/engine mating surface.

Out of curiosity (of course otherwise why would i ask) what is the thickness of your plate between the pan and the engine?

Happy 4th

Rich, my engine is a 1988 13B, normally aspirated, aluminum plate bed mount, so the engine is held in-place by the oil pan bolts.  The aluminum plate and engine mount are of my own design and construction.

FWIW:  I had one broken tension bolt on spark plug side of the engine; not exactly sure which one but it was around the 10 o'clock position if looking at the bolt heads end.  The bolt broke in the threaded portion right where the threads were no longer engaged with the housing ... this was posted way back in 2011 ... see message #53485.  Jeff
