I was asked to show how I made some extensions for my G29 pedals, so here we go 
These extend the arms by 36mm. This is the distance between the two screws holding the pedal plate on, so the lower screw ends up screwing into the original upper hole in the arm.
The top screw has a nut on the back:
The big 22mm hole allows the original plastic risers to fit snug against the extension:
Side view showing that some of the sides needed trimming to avoid hitting the case and leave that screw clear:
The three screws holding the extension solid MUST be short enough to avoid hitting the piston:
These are the dimensions of the aluminium u-section that I used. It's quite hard to find with short sides - I would've preferred 1/2 inch, but 3/4 inch was the closest I could find:
Optional replacement riser, which would avoid the need for the large hole...
Wooden replacement for the plastic riser, that I'm using to get the pedals closer to the arm (more like G25/G27). This was the tester! To avoid chipping like that I did the holes for the rest before cutting the wood. Top is curved to match the rear of the plastic part of the pedal plate, just done with a hand file and sandpaper.
Template for the drilling etc was done in kicad (not an ideal choice, but I had it loaded!):
Kicad project files attached. Its printing comes out with correct dimensions on my printer...
