Using Leon's plans, I drilled the holes and bolted the steel pillars to the sills. Then when I tried to fit the rear seat pan, the flanges where the pan should sit on the sill will block the holes for the steel pillars. Is this common? I think I could first position the pan on the sills then drill thru the holes in the sills where the pillars fastens, then bolt in the pillars, OR am I missing something. THINGS ARE PROGRESSING.
you have the pillars in the wrong place or you have the wrong pan.charley
