5K Loose Radiator

[Steve Sherman]

I was doing a general fluid check & top when I noticed something odd,
the radiator is a bit loose and has sunken on one end about 1/2".  There
is a fair amount of forward and back play at the top, probably about
1.2" again without putting too much force on things...  No leaks, and
but this looseness has me concerned.

In looking around the only obvious thing that I sould see was that the
bracket that goes from the front of the car frame to the top of the rad
is missing (the one with a stud that goes thru the top cowling).  No
sign of it, so I will hit a junk yard for a replacement.  This can
explain the forward and back play, but not why one side of the radiator
has moved down.  (I have not crawled underneath yet, as it is snowing
here)

Any thoughts about what could cause the radiator to sink like this: a
missing rubber bushing on the bottom?
