hardest part for me would be doing the pedal.... back under the dash again... although. i would have the intrerior out for cutting/welding... wouldn't be too bad
The hardest part of that is deciding if you want factory pedals or not.
I went with Triton pedals, I got each pedal individually so I can set them for my wide feet, even factory A body ones are too close together for my liking
But they also make a bolt to the floor 3 pedal kit that you’d just have to run lines thru the firewall.
