Jim F, that's the way I plan on doing mine(want to use the original seat).
However if you are going with a new seat check out the late 90's Dakota.
They have the seat belt shoulder built into the seat back. There is '56
here and that's what he used and it looks great, has the fold down center
arm rest and all!
