I’m adding a console to a ‘71 Duster 340. I bought the car with the previous owner switching the steering column and installing the shifter on the floor. A stock console came with the car. I need to know how to find the placement of the console mounting brackets. Are they welded or bolted on to the trans tunnel? Is the trans tunnel marked for the placement of these mounting brackets? I haven’t removed the carpet yet to check. Any advice or information would be greatly appreciated.
