engine high on driver side

The mounts really only fit one way. It's not like the biscuit mounts that can set high on one side if you aren't careful. Time to start measuring things.
Hey Jim...thanks for the in put I believe I need to start measuring some frame work..just a little info on the car. 67 barracuda, 73 front clip all new equipment. I have had this car for 35 years, its never been wreaked....Its a full tub/back half with 29 18.50. Roll bar and a full 2x3 frame. This car is 95% completed ...Im thinking something went south during the frame work ...i was told that all the frame work was measured and correct. I'm not so sure about that...I will let yall know what the out come is soon. thanks again
