And the cable reaches.  There's about 2 inches of play with the cable after the bucket is on, so it's a much tighter fit obviously than before, but there's room to thread the cable without any strain.  Though, you still have to be careful.  There's room, but not much.

Just need some minor repair on the SCSI board itself and I'll be able to test it.

I'm wondering if it'd be any easier to just flip the board around.  I'll have to experiment.
