Which pedal set for manual conversion

[Goran]

I have a LHD manual pedal box and RHD pedal box I got from A8 parts.
I will bring both to the owners meet on the 15th of June.

I originally wanted to install the LHD pedal box because the mounting points are essentially the same as the RHD pedal box.
The main obstacle to this is that the mounting points and hole for the brake booster are on the wrong side. I was hoping to physically move the brake booster to make it connect up to the LHD box, but there is no room to move the brake booster because the body work wont allow it. You can easily see the brake booster when you open the bonnet.

My next idea was to mount a custom clutch pedal to the standard RHD pedal box. There is enough room to do this. The problem here is that because of the brake booster clevis and piston which protrudes into the pedal box, there is barely enough room to mount the clutch master cylinder, but I do beleive it is possible with some clever aluminium welding and machining to make custom mounts for the master cylinder.
Then the additional challenge is that you would needa custom over-centre spring for the clutch pedal.

I am planning to buy a second had A6 C5 manual pedal box, I'm hoping the easiest solution may be to machine off all the protruding bits (on the inside of the footwell) on the A8 pedal box and weld the A6 pedal box onto the A8 pedal box. Then hopefully all that would need to be done is change the clevis on the A8 brake booster to the ball connection that the A6 pedal box uses.

Then I need to find someone who does aluminium welding. Do Unit 20 do aluminium welding?
