Ed:
If your spar attach bolts are too long I have what seems to me a better
solution.

Since you are bolting composite materials together why not cut two aluminum
spacers of the required thickness to make the bolts fit and make the spacers
larger than the bolt by 4 or 5 diameters to spread the compressive load more
evenly over the composite material.
I agree with Rob.  Friction will help but he bolts MUST be designed to carry
the entire shear loads.
