4Runner Seats into 90 PU

[MarkReye1]

Hi all,

What a pia the seat install was. I have a 90 4x4 Ext PU, and I installed the driver's side seat from a 94 4Runner. The seat is comfy as all get out. However, the seat brackets lined up with 3 of the 4 holes. I was under the impression that these 4Runner seats were a direct bolt in.

Did I miss something, or have others only mounted 3 of the 4 holes.

Please advise.

PS The lumbar support is the bomb.

Nope, same thing in my 91 std cab with 94 4R seats. Only 3 of the 4 lined up. Easy enough fix though.

Ok, I did not want to think I was up poo creek, with no boat and paddle.
How do you fix it to have the seats secured by 4 bolts. I do not have a tap and die set.

I dont' know how different the mounts are than my 4Runner, but I drilled out the holes on the seat itself.... Still very strong, by the way. Here are some pics.

Jerod,

What size drill did you use to drill out the mount. I imagine you drilled out the right front bracket on the driver's seat. That is where I am off, and I am off quite a bit.

I started with a small bit to get my center in the right place then went up in sizes until it fit.... I think it was around 1/2 inch...

Jared,

I am one inch off of where the bracket is now sitting, verus where the mounting hole is located. What thread tap can I use to secure it, otherwise I will have to fab up a piece of flatstock and jb weld it to the mounting bracket and secure it by the normal bolt.

As far as drilling a new hole in the floor board, how do I get the bolt to be secured if I drill a new hole to secure it to the floor board.

If anyone is local to me in Pompano Beach, Ill gladly pay in beer.

Here's what I had to do as far as redrilling holes. The outside holes on both front mounts were drilled out and with a little prying fit right in, and both the inside holes on the rear mounts.

Are you talking about the front or rear mounts?

[MarkReye1]

Jerod,

I have the front seat secured in this fashion. If you are sitting in the seat, I have the left front secured, left rear and right rear mounts secured with bolts.

The right front mount bracket is one inch or so away from the stock mounting hole.

If I drill a hole into the floor the truck, I would need to secure a bolt with a nut to the mount so the seat will be held by 4 bolts.

I may have to fab a bracket from flat stock, drill two holes and mount a grade 8 bolt backwards where the head of the bolt is flush against the floor and secure it with a wing nut or some other nut, and install the other bolt through the second hole and voila, secured seat.

Im open for ideas.

If the rear bolts are mounted, the front is the easy one to change, because the front bolts go into the raised lip thing. You should be able to drill a new hole through the lip thing and get a washer and nut in behind it by cutting a little hole in the carpet if there isn't access already......

[MarkReye1]

Jerod,

Im going to take a picture of the seat mount. I have an inch offset that I cannot make a new hole for on the mount itself.

Mark

[2ndGenToyotaFan]

Yes, pictures are good....

[MarkReye1]

Jerod,

I sent it from my mother's cell phone to my email, and I am having trouble pasting it to here.

Ok here's an idea.... I measured! My stock mounting holes in my truck 89 4Runner (Not on the 4Runner seats Which were from a 90, maybe by 94 they had changed them....) is 17 1/4 center to center. What do you have in your 90?

[MarkReye1]

Jerod,

I just measured the mounting brackets on the seat versus the mount holes on the truck.

The 4Runner Seat brackets measure 16.75 inches. The stock mounting holes are 15.5 inches. I measured the center of the hole where the bolt would be and measured accordingly. If I started from the start of the bracket to the end of the bracket, then I would get the same measurement.

Hope that helps.

Ah Ha! So I had to stretch the 90 4Runner seat mounts by 1/2 inch (not a big deal by redrilling), but you need to squeeze it by 1 1/4 inches.... I think you will have to pull the carpet around the front mounts and drill some holes and put a bolt in from the front and a nut on the back side where it's "open" (labeled in the picture).

In this picture you can see the stock nut (circled) that's welded to the back side of the mount, because he cut it open and folded it forward. You can see if using the left or right stock hole will put the seat centered enough for you, and just drill out one hole for a bolt and nut, but you may want to center the seat around the stock holes if it seat doesn't feel right.....

[MarkReye1]

Jerod,

What size nut would work with the factory seat bolts? I can drill a hole where the seat mount is now located.

I have spare 14mm bolts from a different toyota seat.

Thanks,

Mark

I don't know off hand, but if you take one of your bolts down to a hardware store they can help you figure it out, also get Grade 8 nuts, and a washer couldn't hurt back there either.

[MarkReye1]

Jerod,

Thanks for the help. However, one last question, how do I get a nut behind the screws, would I access it from below, or behind the raised lip?

Mark

Behind the lip inside the truck, your carpet may have a cut behind the lip, mine does, and with the seat out you can pull it up pretty easy.
