PDP-11/34 rails?

[Josh Dersch]

Hi all --

I'm looking to rack up my PDP-11/34 so I can get it off my bench.  I'd 
like to track down something similar to (if not exactly) the original 
rackmount rails (the ones that allow the chassis to pivot 90 degrees so 
you can deal with the backplane easily), but I'm not sure what the 
original part number or manufacturer was.  Anyone have this information 
handy?  Better yet, anyone have a spare set of rails handy?

Thanks as always,

Josh
