[oletrucks] radiator for 58

Stephen--

The radiators may have had some small changes in 58, but I have a 56
radiator in one of my 59s, and I've had a 57 radiator in the other 59. 
My 57 Suburban came with a 60 radiator, it fits fine and looks just the
same except it has a notched area on the top tank to clear the hood.  I
think you can safely swap radiators between all the 55-59 years.
