Question for Harrison owners

[leroy17]

Easy to solve. I gained nearly 100mm on those two pedals and 140 on the accelerator

My Harrison had the xf (for memory) brake and clutch pedal set up. There are a few mods to do. Take the assembly out, get new shims from rare spares to tighten it up a bit. There should be two bolts through the firewall, and two under dash. Where the firewall mount is, you can could cut about 20mm off the end and weld in another mount. I didn't do this, I just straightened it up nice and square, welded up the seams and this gained about 10mm.

I used 50mm flat bar as a brace across the top of the assembly picking up all fixed locations, welded in and this eliminated the flex in the pedal arms. The arms have a forward protruding section that the pedal pads were mounted to ( think like a hockey stick). Cut these off and gain 50mm. I then used the AC pedals from finishline, drilled and mounted these the the arms.

Now..... These were now at an awkward angle on my feet to use so I cut a 'v' shape out the back of he pedal arm, bent the pedal to close the gap and welded and braced. The cut a bigger v in the front, bent to close the gap, braced and welded. This then both corrected the angle for the pedal pad and also gained another 40mm.

The accelerator pedal was easy with some creative bending, cutting and welding of the pedal arm into the correct position. Also changed the cable mount to be a little bearing rod end for smooth operation and also used Teflon shims on the pivot so there was zero play in the arm. Also, make sure the pedal heights are all set right. My car originally had the brake and accelerator level with each other and the clutch even more forward.

Finished result was brake and clutch were level and acceperator was about 50mm further set in. No flex on any of the arms, no play in the bushings, heel and toe were perfect, and transition from depressed brake to accelerator was natural.

Sure, sounds long winded, but once the assembly is out, these are easy mods. The overall difference was great, both in the solid feeling and extra 100mm of foot room. I am 6"1' with size 12 and was comfy in a NON extended harrison.
