reinforcing the floor - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I picked up a set of 40-20-40 seats with integrated belts in them. I want to reinforce the floor to accommodate the seats what do you all think is the best way? I was planning on welding some plate underneath the entire cab, but honestly I haven't been to my friends shop to see what the underneath looks like. Something like 16 gauge.

Any thoughts?

Oh and I got the seats and console out of a 04 for 150 bucks without a blemish on them!

I always put a large grade 8 washer or a piece of metal plate under the nut on the underside 2" to 3" round

I've had a 60/40 in mine for years with just through bolts with large washers underneath.

I look at it this way.....the front mounts see very little tension because the seat back rests against the back of the cab. The seat belts anchor to the floor (stock location), so what kind of situation is it going to take for the seat to pull through the floor....I can't think of any.

Yes but his have the seat belts in the seat it self so now all the force is on the mounting harware. Do a search for "Project Lemon Drop" and you will see what I have done on several of them now. I use 2" x 1/8" plate and try and tie/weld it to a few different places but do not weld it solid! Also round off your corners so they do not act like a can opener if in a wreck. Then I use the square nuts for mounting because you can weld the corners with out weakenig the threads.

Or you could get some Steel from your local hardware store (Lowe's, Home depot, etc.) and do this. Just use threadlocker!
