vents on '66 marlin

Those are A/C ducts.  Does your car still have the A/C system installed.

I just looked at some images on line.  Looks like maybe the controls were under the dash, and they replaced them with the cust-o-matic A/C?

My '65 Classic had factory air; those are the vents for the factory air at dash level. What has probably transpired over the years with your Marlin is that the factory A/C went dead and the owner at that time replaced the inside equipment at least, with aftermarket or dealer A/C parts. Mine was missing the compressor, condensor, lines, mounts, and control head, so I removed the rest of the interior parts and modified (simplified) the evaporator box to function as a simple heater plenum.  The center vents are probably the clunkiest looking part of the factory A/C system IMHO, and Rambler didn't have the space to add "normal" A/C venting behind the dash like many other domestics had. I fabricated a dash insert to close that space until I locate a proper Rambler part.

Oh hey, I just noticed you are located in Austin... you should know about John's Auto Salvage in Seguin Tx.-they have a good selection of used parts for these mid sixties Ramblers ...even a '66 Marlin which can be seen in the picture album mentioned above.

...FYI most other cars did not come with A/C back then... '69 AMC Ambassador was first US car to have A/C as standard equipment!
