no they did not. Is the CMC trim unit just the bracket that bolts to the transom, then you hang the motor off the trim unit?
I would recommend switching to a Panther integrated trim unit. They made an actual trim unit that fits all the OMC 20-35hp motors with the through-tilt-tube steering style stern bracket, not the smaller older style fastwin style stern brackets. I have one installed on my 1984 35hp model and they look nifty, work fine, and IMHO are better than the CMC products.
