When I installed mine, I increased the bolts that fasten down the seat from 5/16” to 3/8” and upgraded them to grade 8. I also added a few more welds on the seat tracks where I thought they were lacking.

I know that they are not up to todays standard but at least I feel better riding in our truck.

Here is a link explaining how I installed them.
