How about rebuilding a 69 carb to SD specs and run that.

This is what I was going to type until I saw Boss's response so I'll just quote it.

I would not modify a genuine lower pan. I would get a repo to modify.

Doesn't the 70 RA pan have the vent hole in it already? If so I'd get a repo 70 pan & leave the original one alone.

I've seen guys cut the stack off of the carb vent too. If the SD vent isn't different than a 71 & up Q-jet maybe that's an option.

You are correct Steve. An original or a repro 1970 pan would do the trick for you and will look exactly the same as the 1969 pan until you remove the lid.

The 1970 pan accepts the 1970 California emssions carb which also has the stack like the 71 up carbs have. The 49 state Ram Air lower pans in 1970 got the rubber plug.
