These are the pics of my Roll Bar install and the custom tire mount I made for the roll bar that is fully adjustable for any tire size. I have had it in a few weeks now and I love it tire doesn't move one bit and everything looks real clean. Let me know what you think.

looks good

Pretty slick with the Tire Carrier. I like it. Looks real clean. Good Work.

Looks good.

I'd consider putting some reinforcing plates on the underside the same size as the mounting plates on the roll bar.

I second the plates or at the very least some much bigger washers.

Extremely clean install though. Very nice. Also diggin the tire mount that you came up with. Mine is just ratchet straped to the boxed metal plates towards the bottom of the forward legs.

Nice Job!

Yes I agree with the plates or washers. I have already gone ahead and put much bigger washers on those are actually pics from the first time I bolted it up. The washers are not to big that they overlap but big enough that they almost touch I figure this should work just fine.

Looks nice!!
Can't wait to get one of my own...

IMO, if you are going to wheel that rig and bounce around w/ the spare tire attached to the roll bar w/ only the mounting in the floor sheet metal as bolts w/ washers/nuts...the metal is going to fatigue...not if, but when...and pull loose. It isn't reinforced in that area at all like it is in the 1st gen mounting area...so I think plates are not an option but a must - washers ain't going to cut it in the long run.

Not trying to toot my own horn, but I got a pattern that I made for reinforcement plates when I fabbed up Rock Slide's roll bar and I'd be happy to make you some if you are interested.

It is a nice clean install, but I just don't think washers will get the job done in the long run. If you didn't have that spare tire on there, no problem, but I think that added weight will fatigue that sheet metal if you wheel it like that. If you are a mall crawler...no sweat.

EDIT: Please see my other post below for clarification.

Agreed. The 1st gen roll bar in a 3rd gen is IMO mostly an aesthetic modification while providing some added protection, while slight, and provides additional places to mount tires, Hi-Lifts Jacks, mag lights, Power Tanks, etc. In an on-road roll at highway speeds the wheel well sheet metal will shear regardless probably, as only a roll bar/cage tied the frame provides any real life protection. In an off-road flop or roll over it will still probably punch through if you get any "mashing" on the roof as the wheel well sheet metal is just not reinforced anywhere. To clarify my comments earlier, I was merely suggesting the plates for reinforcement, so the bolts don't pull out/punch through/wallow out with the spare tire bolted to the roll bar, not to make it a "real" functioning roll bar.

What tubing is the 1st Gen rollbar made of (OD & wall)?

One in my 85 was 2" O.D. and looked like 11 gauge or less IIRC, never measured the wall thickness, but I know it is 2" O.D. as I had some clamps for it for various things.

Thanks Wabbit!!

I think if we consider that the 3rd gen 4Runner's body in stock form will easily withstand a slow speed roll over without crushing, then the roll bar will only help. Even if only just a little bit.

I don't think any of us are doing this for roll over safety though. Just like Wabbit said it is simply a mounting point for stuff. That it is from the 1st gen Runner makes it that much cooler. The 1st gen got all this started.

It doesn't seem like the roll bar is supporting any of the spare's weight so the fatigue seems minimal.

If the spare tire is attached to the roll bar as it is shown, the weight force will be transferred laterally to the roll bar as the 4Runner shifts side to side when wheeling. The floor of the cargo area will support the weight of the spare tire vertically. The dynamics of the weight forces (means there is more than one force of the weight in more than one direction) change as the 4Runner rotates its horizontal axis on the horizon (like the picture on the altimeter/incinometer on 1st gens).

Again, if wheeling it will be more of a factor, if on-road use only, I wouldn't worry about it at all.

Thanks for the posts guys I'll consider building some plates but will probably just wait a while and see how the washers affect the sheet metal.

My buddy actually Rolled his 4runner 3 1/2 times at 55 mph and walked away no problems. His 4runner is still driving around today the rear and the front of the roof were dented in a little here and there but the body shop just pushed it out the best they could and he has a 4runner that runs and drives and doesn't look to bad unless you get real close lol. I'll just say I'm still happy to have my roll bar even though I don't plan on ever rolling my 4runner.

Not sure if this is what you are refering to or not but it would take a lot of substantiating information to explain what is being seen in those pics.

Reguardless, Cool mod and keep us posted on what you come up with.
