Finally got my two new fronts seats in.
Used the STOCK seat bracket with two plates welded to each to create new mounting points for these aftermarket seats. However, the stock mounting points are still usuable, meaning I can switch back and forth between stock and these seats at will.
And since I used the stock brackets, the power controls on the drivers side still work. Well, the back and forth and up and down still work, the power tilt is non-functional. Still not too bad.
