BJ71 Rear seat belts

[audaciousduo]

The JDM RHD BJ71 I picked up as the core of my project had no rear seat belts when I got it. No problem I thought, but when I drilled an exploratory hole on the upper C-pillar where the Canadian BJ70 shoulder belts were anchored. They are not there and I could not find any sign of reenforced captured nuts in that location. I'll use the small holes for rust proofing and put rubber caps in them but I still need to install rear seat belts for my kids. The truck will see a lot of use with my kids in the back on those back country camping/wheeling/fishing trips. Where are the the seat belt anchors on a JDM 71? If anyone has one and can measure them out or take pictures I'd be a happy guy. I assume they are just under the head liner some where and I can find them with a pin if I have a rough starting point.

Thanks in advance

Did a little digging on Toyodiy.com. Looks like the JDM BJ71 had lap belts only in the back until it went away in 1990.

So, the lap belt re-enforced anchor nut should still be on the wheel well.

The 71 is a 1989.

put in a roll bar with your anchor points.

My hz73 has a factory internal cage that the rear shoulder belts fasten to.
Dave, if you need to take some measurements for the cage I could come by one day so you can take a look.

I may have to do that. I kept the belts out of the Canadian 70 so I'm sure I'll come up with something. Weird the JDM 71's have no rear belts at all.

I had a thread on this awhile back for my Dad's 73.
He ended up buying some ones from a MG place in Vancouver.
He had a bunch of different styles to choose from.
Pretty easy to make them all lap belts.

Pm me if/when you're ready to take some measurements. My schedule is pretty open at the moment.

Will do. Is your roll bar plated on either side and tied into the frame?

If you're using a custom roll bar you can tie in however you feel necessary.

If I were you I'd just cut out some holes and weld a couple of plates with captured nuts up on the support poles, and do the same for tha anchor points on the floor.

On my HZJ73, I'm using a factory roll bar which has welded-on raised platforms with captured nuts on the rear wheel wells as anchor points for the 'plated' roll bar. I'll put up some pictures in the build thread as I progress.

Thats exactly what I was thinking I will do if I go the roll bar route which I likely will.

Thanks

I've never really taken a close look. It's full of gear right now so I can't tell. I'll take a look when I clean it out.

I had additional seat belts put in by a licensed installer when I put a forward facing bench seat in my Troop carrier. Later I wanted to upgrade soem things that required me to remove the belts. Essentially they had just drilled through the pillar and put a plate behind it that had a thread in it. SO the load was spread over a greater area int he sheetmetal. SInce then I have had a look at other vehicles and it seems to be a common way around it.

As I was installing new seat belts I though I would upgrade their job. SO I got thicker plate, cut the thread in it, filed off the edges so it would not crease the emtal when done up tight. I then drilled a hole in the plate from one end. This was so I could rest the plat on a piece of wire to install it up the pillar as there was no other access. I have seen others do it by welding on a a piece of thicj wire. However if you do this the wire can vibrate and drive you INSANE with annoyance.

So I then pushed the backing plate up the pillar intil it was in roughly tyhe right spot. I then got ready with my seat belt anchor and bolt and in a surprisingly small amount of time got it to start screwing into the plate. I then did it up FT ( I walways use loctite and the highest grade bolts I can).

And thats it. Better than what was isntaleld by the licensed car body modifier.

Hope this will eb of some use. If this does not make sense let me know and I can provide more info.

Kind of what I was looking at doing. Thanks a ton
