Thank you for the input my dad is taking the mounts to his fab guy today. His fab guy told him once the carbon fiber is pressure treated and sealed its 10x stronger than steel. He didn't specify if that was on a horizontal stress plane or vertical stress plane. Ill be sure my dad describes how the load is supported by the mounts and see what his guy thinks. If all else fails I'm having my broken mounts welded where they broke and cutting a spare set out of some 1/4" diamond plate aluminum we have laying around in the shop. Also the mounts aren't under an extreme load like my broken ones would indicate. I installed the spacers wrong which gave zero room for movement of the motor. Basically I broke the mounts not the design of the mounts or the engine. Again thank you for the info really appreciate it cause its something I didn't know and wouldn't have shared with my dads fab guy.
