I have used the CRG and OTK front porch kits… They are similar and both mount where the lower bumper bar goes so either will fit most modern euro chassis.. I found both used. don’t sweat a missing brake rod you can get those in the length you need. The OTK kit mounts the “pan” level with the bumper bar.. The CRG one drops the pan about 1/2 inch below so the OTK one holds you feet a little higher up..
Both kits extend the pedal mount out about 3-4 inches. Fabricating a kit would not be too hard either. New the factory bits are $$$ but used mine were quite affordable.
PS . I am 6’4″ tall currently using the OTK bits on my 2008 Gillard
