I would not mess around with an engine mount.
I bought a project with an engine and mount. However the
mount looked too weak to me so I bought another from
Weldtech. The new mount did not quite fit the aluminum
extrusions so I moved 3 of them. It really is not a big job
to move them. Just get help from someone with a lot of
building experience.
Do you belong to the CSA? If you do, then you have a directory
of all of ther CSA members in CO There are 23 of them, including
2 in Denver. I think some of the others are in suburbs of Denver.
If all else fails go to Falcon and see Burrell Sanders. He rebuilds
or finishes Composite airplanes fulltime for a fee. He knows his
business.
