The rotator ring mechanism in the 575, and perhaps other scopes of that era
was made of nylon. The nylon splits, and the back end of the tube can
flop around a bit. Not alot mind you, it's still in a metal shield.
As Ed said, if you take care, don't drop it, don't knock it about, you
should be fine - at least till you can get it down on the bench and see
what state the mounting hardware is in.
I do agree to keep it off its face. If there's any loose bits of glass in
the tube, they'll for certain mark the phosphorus, but if that's the case,
the CRT will be suspect anyways.
Short of removing the CRT, and transporting it separately, I'm not sure
there's much else you can do - beyond being careful - of course.

Paul,
I used to haul large CRTs (21" computer displays) this way, which are
admittedly less finicky than an old tek scope, at least they never seemed
to care about orientation, and I would seatbelt them in. They were all deep
enough that the seatbelt was near its limit, so they were held in pretty
securely that way. For this, however, I will try to pick up some bungie
cords or something, to get a good strap around the seat back. I was going
to bring some larger blocks of closed cell foam to give it some cushioning
in case I had to put it in back, but I can use the same foam to wedge
against the dash in front.
I'm still a little worried about the CRT mounting in the case. I can't
seem to find the thread now (and maybe it wasn't in this group; maybe it
was in a Facebook group I also belong to) where someone had moved a
500-series scope but some part of the CRT mounting hardware had failed and
the neck had shattered. I'd really like to avoid that sort of tragedy if at
all possible.
