FWIW ... I haven't had either problem with my '84 or my '85.

I've been driving my '84 since '91 and haven't broken an exhaust support
rod yet.  My muffler strap finally RUSTED apart a couple of years ago
and the replacement is doing fine.

When I got my '85 all the exhaust support rods had been removed and
discarded by a PO or some "Mechanic".  I scrounged around and got all
but the one that angles upward from the J pipe to the side of the
exhaust pipe at the head.  For that one I just put on a turnbuckle which
  is working like it was supposed to be there.
