I have an older Holy Grail pedal and I was wondering if there is a place to order replacement parts? I have the older classic chassis version.

1. I am missing the screw right below the reverb-selector switch. See photo:

2. I was wondering there might be a replacement metal chassis for this pedal? My pedal is extremely worn. Worn is cool, but I want to make this look mint again.

Any help would be great!
