Adding a 3rd seat
just picked up a blazer rear seat to add to my burb as the 3rd seat. Anything I need to know about mounting it for safety reasons or just drill some holes and throw in some grade 8 bolts?

Re: Adding a 3rd seat
I also would like to hear from someone who has done this since this project is in my near future. I am also installing the narrow 2nd row seat.

Re: Adding a 3rd seat
There should be some holes, or at markings of where they would go, on the floor to mount the brackets.
Do you have all the correct brackets?

Re: Adding a 3rd seat
I have the correct brackets but my burb never had a 3rd seat in it before.

Re: Adding a 3rd seat
Well, I can tell you that the existing rails are either too close to the 2nd row or too close to the back. The gas tank is in the way of inserting a bar/rail for the perfect position. Instead of dropping the tank and going through all that, I just mounted the rear brackets of the bench to the rear most rail. I am assuming you want to mount through some steel and not just the plywood.

Re: Adding a 3rd seat
If you go through the wood place some wide washers or plate on the bolt head to distribute the load to a wider area.... so as they don't rip through during an accident. Thats essentially how it looks like the factory did it. (Large metal plates with threaded nuts/heads screwed into the wood)

Re: Adding a 3rd seat
I figured I could just drill through the wood and use a piece of flat iron to run the length of the seat underneath to attach all the bolts to.

Re: Adding a 3rd seat
Have you done this yet? My assembly manual indicates the holes are there with plugs in the plywood

Re: Adding a 3rd seat
I have not done this yet. I will have to look for the plugs next time I'm in cali, since that is where the burb is.

Re: Adding a 3rd seat
Here's some not so good pictures of the bottom. The front of the seat is bolted to the floor with 2 very expensive "c" brackets. They bolt to nutserts that are nailed to the bottom side of the floor. The back of the seat bolts to the metal brace underneath. I believe the seatbelts bolt to the same brace.
