Hello, it’s been awhile since I’ve posted, but looking for some help. I have a 68 Firebird with original 400 and original factory air. Trying to do my own mtce on tune up and looking for assistance on best way to go about changing the spark plugs. The plugs on the driver side of motor are simple, but the plugs on the passenger side are not accessible due to AC being in the way. What is the easiest way of getting at those plugs? Thanks, Jay
