I have access to a rotisserie already set up for an RV8. Here is my question. The builder who gave me the rotisserie first drilled and mounted his motor mount, then fabricated the rotisserie mount based on the holes he drilled in the firewall weldments. I do not have the motor mount and need to know how to drill the holes in the firewall. Are the factory holes in the stainless firewall accurate? What would be the minimum size hole to use, knowing I will have to enlarge them when I get the motor mount? Are 1/4" bolts big enough to hold the structure? Are the motor mounts from the factory 'real close' to the firewall holes (less than 1/16' off)? I suspect the jig they use to build the mounts is 'exact' to the plans, but I have heard that no 2 mounts are exactly alike.
