Looks good. Do you know the year the seats came from? Cause i didn't have to modify anything. Then again it was going into an 87 PU not a new 90's style.
It does look like you are on track there. If you have to drill the bed, make sure to use some silicon and seal it so it doesn't leak into the cab.
Also why not fab up a little bracket to hit the one missing bolt hole and leave your seats in one piece?
