I believe the 55 and 56 are the same. I know 57 is quite a bit different.

In looking at the three supports, the 55, 56 look like strait metal to the fenders, the 57 has a arc in the attachment aera to the fenders, don't know about the width and depth comparisons ?

All three years are different and are NOT interchangable.

Thanks Gene,

I wasn't sure about the 55,56, but I knew the 57 is not interchangeable..

The supports for the radiator between six cylinder position and V8 position are different too.

 

Correct me if I'm wrong, but isn't only the tie bar different?

 

I bought a 56' last year just before I bought the 57' and the radiator in the
56' was a fairly new heavy duty one so I swapped it into the 57' before I sold the 56'. Have not had a problem and it fit right in. That said, the cross member on my 56' was cut and didn't go all the way across so maybe the PO bought a 57' instead. Does that all make sense?

The radiators will interchange, the core support won't.

The cross bars are different for each year.

The saddle is the same or close enough for all years, but 6's are different from V8's. There may be some minor variations - the 55s used 3 different designs but I think they will interchange.

The filler panels are year and perhaps option specific also.

 

Thanks

Thanks for the help

Just found this thread - I posted an answer to your thread in the Chit Chat forum, so will post here as well.
The 55 top bar is about 3/4" narrower than the 56. Measurements are 3' 8 3/4" for the 55 and 3' 9 1/2" for the 56 - both meausurements are at the front bolt hole.

56/57hybrid support

I needed a V-8 radiator support for my 56 so I spliced the top bar onto a 57 radiator mount,
It looks like it will work, or so I hope!
