6-way seat track for A body?
It’s possible it might be a direct bolt-in or with drilling a strategic hole (or a longer floor bolt) work. I am adding a 68 Power rack out of a 68 C Body wagon to my 65 Dart. Other than one mounting floor bolt being too short, it bolted right in where the original holes were for the bench seat. If you go with the 6 way, post pics on how The install goes.
EDIT: i should have stated the power rack was virtually a direct bolt in to the outer bench seat mounting hokes and INNER bucket seat holes.
