Manifolds, Carbs, Gassers, Gas Tanks, Intakes for Rat Rods

Gotta have the right intake manifold.
These old cars have carburetors that are going to need some tweaking.  You may be able to find a rebuild kit pretty easily too (use the search bar if you need to)
 
And boy, a new gas tank is one place you don't want to scrimp.  Get a solid tank so you don't explode.
