Here is a picture of the alignment on my double tripod motor mount
and the combination PSRU plate and motor mount.
The SS taped to the bench is the old firewall the former owner
made for the Lycoming mount. The plum bob locates the exact 
thrust center line mark on the old firewall. 
When I get that drilled I will use it as a pattern on the new. 

The 88 turbo exhaust manifold is a weight to balance and level the plate.

These picture are largely self explanatory
but don't be afraid to ask questions.
