Technical Cadillac 2x4 intake differences between 1956 and 1957. Are there any?

Are there any? I am considering buying an intake for my 56 caddy with the 365 engine. Mine ended up being cracked. The intake I am looking at is from a 1957. Is there any difference between them other than part number? Height? etc.
Thanks in advance!

 

I don't know sure but it will bolt on and I doubt it is any taller.

 

The 57' is a bolt on. Is yours unrepairable?

 

I'm pretty sure that the '57's have the larger bolt pattern for the carbs while the 55-56 have the smaller bolt pattern. ....

 

That is correct...
