I spied this on eBay and felt sorry for it:
I think it's a 1974/75 Ripper, there's no other clues like pot codes to pin it down further, but I'm going to err towards '75 due to the magnitude of the serial number (574623).
All I've got with it are 8 half pressed in frets (now removed) and the three mounting bolts for the bridge. It's an alder bodied Ripper, so it's nice and light and the ebony fingerboard is a nice bonus - I do like an ebony fingerboard. So I've got a lot of parts to find.
I'll be trying to bring this back to as close to original as I can, but I will be changing a few things.
It will probably be wired like the second diagram in this file:
http://www.ak-line.com/medium/L9-S_Ripper_Neck.pdf - out of phase wiring is horrible. Just because one CAN do something, doesn't mean one SHOULD. Maybe I'll try both and see.
It will have a period incorrect 5 ply pickguard (I don't like single ply pickguards)
I'll probably end up reaming out the holes in the headstock for some Schaller BM sized tuners instead of the weird sized ones that used to be on it.
I fancy refinishing it like the "wine red" that some Grabbers came in:
I should be able to find most of the things I need, but I'm currently headscratching about the truss rod cover and the string through ferrules for the top of the body. And if I can't find any old Ripper pickups then I'll have to take a deep breath and empty my wallet in Seymour Duncan's direction...
