Hey kind of a crazy question, but bare with me. Would it be possible to take a aluminum tub of a Toyota Fj40 and putting it one a Jeep wrangler. I looked at the dimensions and they look pretty close. What problems would you run into?

Be cheaper and easier to buy one then.

Mounting won't line up, need to match up two incompatable wiring harnesses. Make the gauges work. How does the steering gear line up, foor pedals, shifter. Is the gas fill evem close.

Too many unforeseen issues, and in the end it would be a basketcase. It would be easier, more practical, and less expensive to just trade the Jeep for an FJ.

I like bacon.:)


My suggestion is: Go get some bacon, have some breakfast, then go out and enjoy your TJ.

Years ago I had a CJ5 on spring packs four inches thick. Rode like a tank, zero travel nothing electrical worked except what I had rewired. I went from that 73 to a 74 FJ 40 and the difference was night and day. Little details like front disc brakes and a light to tell you the parking brake was on. Little things but still a whole different animal. I really regret getting rid of the FJ but fresh out the Navy, didn't know what I had. Now FJ to TJ, another story altogether.

What does an FJ have that a TJ doesnt have that makes you want to trade in your TJ for a FJ?

Wrong again. They'll get answered in each of his threads going on at once, then the people responding will realize that and shit hits the fan. Curiosity killed the cat. And insanity is doing the same thing over and over again expecting a different result.

I think your idea of converting would be tough...HOWEVER, just get a non-fully restored FJ and do the rest yourself...you should go to an FJ forum and start chatting there to get some ideas. Sell your jeep first to make sure you have the money.

I bet if you asked the forum members here, they all would be willing to pitch in $5 each to help us, I mean, help you out.

My bad my bad. Don't hate me ok.
Nobody hates you....at least I don't. Everybody starts off green at some point.
But, simple searches can answer a lot of your questions.....Probably not this one.:)

Then again, if nobody posted a question that had already been answered, this forum would be pretty dead except for new pictures.

For the record, I love those old FJ40's. Great wheelers, not so good daily drivers.

I have a friend with a built FJ with a SBC in it. It's very nice, but he just bought a perfectly stock LJ to tow behind his motorhome for the easy wheeling camping trips. I sold him all my towbar stuff I don't need anymore.

I am curious to see this myself. But a question needs to be asked here that I haven't seen yet.

What parts do you want to keep from each vehicle? Are you just wanting the FJ body, bolted onto a jeep frame (I'm guessing TJ)? Or are we talking mixing parts like drivetrain and suspension and such?

If all you want from the FJ is the body, then your biggest problem is wiring and coming up with some mounts. Some of your wiring problems might be bypassed by using wrangler components, like tailights and such. This would require more mechanical fabrication but it would work right, and might even be kinda fun. You may also have to ditch some features the FJ may have until l you can figure out how to wire it right.

I have seen people put H1 Hummer taillights on TJ's, why not TJ lights on an FJ? Of course I say this without seeing either of them side by side, but it still sounds like fun.

Either way though, THIS is gonna take work. Keep in mind, a Frankenstein job like this can eat up that 5-7 thousand dollar price difference very easily. Especially if you have to outsource any of it. If you can fab this stuff by yourself it sounds much more feasible.

Plus Frankenstein jobs never go smoothly. I have an old 69' Fairlane project I have been working on for years, using only Ford parts, that still isn't running right. This is mostly due to wiring, a nightmare you will have with this project. It will be killer if I ever finish it though.
