Pic request: your Edelbrock RPM Airgap all set up

I didn't have to drill and retap anything. The brass fittings I used came with the intake and fit the factory holes.

I'm pretty sure both heater hoses on my 68 are the same size. I know the factory changed to two different sized hoses at some point. If that's the case, then there are reducer fittings available. My 73 Challenger came with a reducer fitting from the factory.
