Well, maybe they changed the hinge design slightly for
the model you're looking at.
Here are some pics of the 7970A with the transport open at 90 deg:

That's about 1-1/4" between the flange and the cast frame.
There's no way you're angling a regular shafted screwdriver in there to
adequately tighten screws.
One could undo the catch that limits the angle of swing, but I still don't expect
it's going to swing far
enough to get the frame out of the way, let alone the PCBs and motors still in the way.
(The black part next to the Al flange is the 'proper' steel mounting bracket.)
Flat-head hex bolts with a shortened allen-key could do it, as long as the tensional
strength of the screw-heads was adequate.
Looking at it, it may be easier to do with a regular screwdriver if the
drive is opened at 45 degrees rather than 90.
Ratchet right-angle screwdrivers are also an option, as are ball-end
allen wrenches or offset-head screwdrivers. None are particularly dear.
In any case, as I've said, I'm not about to hoist my 7970 into a rack.
I lost enough skin just getting it out of the truck into the shop.
I may, however, go prowling for a lowboy EIA rack...
