Well, since the floor pans were out of the 64 vert anyway, we inserted the subframe connecters INSIDE the front and rear frame rails. Welded the seams where they enter the rails front and rear, also stitched inside the rails, drilled and plug-welded them on the sides and welded where they touched the new floor pans.
















Done with colored truck bed liner as an undercoating.



Anyway, thats how we did it.
