I have found a longer clevis pin for the brake pedal return spring.....it's actually a "classic" mini clutch part and plenty are being offered on Ebay. I just have to drill the hole in the right location and cut the pin to the correct length.
I intend on re-using the brake return spring for now, but will get a new spring for the future.
A while ago I bought a replacement gauge cluster in order to use parts from this and my original C8 gauge cluster (which is in a very sorry state) to get one complete set.....but look at the speedo range....
