[FWDLK] Exhaust Manifold Part Numbers

["Rimington, Ken" <Ken_Rimington@xxxxxxx>]

I am looking for exhaust manifolds for my 56 dodge.  I am a little confused
on casting numbers.  I think the same manifold may have multiple casting
numbers for different years.  The ones on my 1956 dodge have numbers that
seem to be from 1955 and 1956.

Does anyone have an interchange manual for exhaust manifolds?

Left manifold is 1634445-3 (1956 Dodge I think)
Right manifold is 1553783-2 (1955 Dodge I think)

I have found some exhaust manifolds, but the P/N do not match and the
salvage yard thinks their manifolds are gold plated.  Part numbers and
sources for reasonably priced parts would be appreciated.  Thanks.
