`35 intake manifold - differences in aluminum and years

[wingerdinger]

I need to replace the intake manifold on my 1935 Ford 1-1/2 ton.
The one I have is cast iron.

Is there any advantage to going to an aluminum manifold, or a newer one if it fits?
I read somewhere that the intake manifold itself is the same from 1935 to 1948, except for the vent/oil filler tube, and the fuel pump shaft, because of the difference in the height at the fuel pump mount.
Any experts on this, please???
I have several leads, but am unable to tell what fits
I am looking for a replacement if anyone has one.
