My best guess would be between "Rod" & "Spring"
Maybe it would help if we knew what guitar you have...
Parts don't look too difficult to make with basic hand tools i.e. Hacksaw, files, drill, small bench vise etc. but I would think it easier to try and find something similar at your local hardware shop that would do the job.
I have a bunch of right angle brackets but they are twice the size that you need.
It may be also possible to bend something out of steel wire (18SWG would probably do the job).
