I went through the wood floor behind the front seats. Lap belts only. Underneath the wood floor got some 4" x 6" x 1/4" plate that the anchor bolts went through. I figure the belts are more peace-of-mind than anything else.
Thanks. Since panels and Subs lack the metal floor behind the seat riser that pickups have, I'm thinking that going through the wood may be the best option.
