vintage air/roll cage 1st gen F-body

[ricer]

not sure if this is the best section to post this in but here it goes anyways.

quick question for guys with a 1st gen F-body. How much room is available under the dash with the vintage air in place? and if there is some room where is it in relation to the unit (dash side, firewall side, above below it).

My car is in the process of being completely stripped and reassembles (similar to what MCC does) but installing a 10pt cage and putting the A-pillars through the dash. So i am trying to get an idea of where to place the dash bar if at all in the car.....
