What are the dimensions of the RV-10 firewall?
Trying to see if i can use an RV-10 motor mount for a lycoming TIO-540 with my plane.
i need the distance between the top two motor mounts, the bottom two motor mounts, and the distance between one top to the same side bottom diagnol distance.

Horizontal distance between the top two firewall mount holes: 40 3/16”
Horizontal distance between to bottom two firewall mount holes: 36”
Horizontal distance between the bottom center two firewall mount holes: 9”
Vertical height of the bottom two center firewall mount holes from the firewall bottom: 2 1/4”
Vertical height between the top and bottom firewall mount holes (the outboard holes): 19”
Vertical height between the top two firewall mount holes and the top of the firewall: ~9 3/8” (ignores the firewall side curvature)
Diagonal distance between a top firewall mount and the (outboard) bottom mount: ~ 43”
