How do slants fit in righthand drive cars?

I made a offset brake pedal for a 56 ford put. Moved the master to the driver's side 6 to 8 inches (center on a firewall rib.) I had 2 steel support blocks made, used 2 brake pedals welded to a 1inch steel bar. Used a 3/8 plate of AL to back up the firewall and an aluminum plate nacho ed to straddle the rib and bolt the works together.

For a rh drive the same type of thing but a longer bar
