Intake Manifold Question

[aero3113]

What are the two protruding half round things on the back half of the intake manifold. I have also seen intake manifolds with them drilled and tapped on the front side of them.

Here is a pic of my intake manifold.

Those little bumps are what the RHD accelerator linkage mounts and pivots on...........andyd

Both my '38 dodge pu and my '36 chrysler have the accelator linkage running from the pedal across the firewall (on the engine side), then to the carb, those tabs are the attachment point for the linkage from the firewall. On my '40 plymouth the linkage went across the top of the head to the carb, simular to the p15 setup.
