This is how I start when a new part needs to be renovated, first I find a drawing of the part I want to start on, this is done online at one of the big companies that sell parts for Triumph.
Why I do it this way look at this page

Now I can see which parts I need to find, when I find the parts that fit I put them in a box, when I have found most of them I start on the renovation of the part

Here is what I currently have found, but parts are still missing, including a spring and some screws, as you also can see on one part, the straight piece has got a bend, this also needs to be fixed again

Now the pedal is fixed and the parts are either sandblasted or cleaned so the next thing is to 2k epoxy primer and finally paint.

Didn’t get a picture of them being primed so here’s one with black paint on it.

Now all the parts are there, including the parts that were missing, they have been purchased, everything is now like the top picture.
