E; hole for electrical grommet

F; I've no idea

G; I've no idea

H; I've no idea


Thanks!

Just for completeness (if anyone cares). That is a photo of a later firewall because the shift rod hole is for a sideshifter transmission. Tailshifters have an extra hole just to the left that allows you to screw in a "ball" for the "socket" for the end of the rod to pivot on.
