I remember the writeup. I printed it for future reference,but don't have it with me. Perhaps it was on thevmc.
From memory:
1. Remove the mounts.
2. Cut them down to size.
3. Weld them back together.
4. Paint or powder coat.
I think they are aluminum, so the welding will be tricky for a novice.
I also remember that this modification moves the boards down and forward. I think he said they now get in his 'space', and would not have gone the full two inches if he could do it over.
That's all I remember. Hope it helps.
