I was wondering about putting a 3B, 12V, into an old FJ-40. Could I just buy the motor mounts from a Canadian dealer for a BJ-42? What will need to be done to put the 3B where the 2F was?
3B in FJ-40???

Do you mean to locate the engine for correct height ,longitudinal and rotational position?
You will need the 3B gearbox .With the gearbox bolted to the motor ,you lift it into the engine bay and bolt the gearbox to the crossmember and the crossmember to the chassis frame.This will give the longitudinal position.
With the engine mounts and frame brackets attached to the motor you lower/raise it until it sits in between the front rails in the engine bay.
When you think its in the correct position ,tack weld it or support it somehow from underneath.
Then fit the the 3B radiator and shroud.
The fan on the engine should have a close to concentric position inside the shroud and not be too close or too far away from the radiator.
Too close and it may chop the rad on the trail,too far away and you will have cooling problems
I say "close to cconcentric" because on 1HZs in a 75 series engine bay the fan is not perfectly in the middle of the shroud
When your happy continue with the welding.
The frame brackets I used on my swap come from a HZJ75 and had tabs that sat on top of the frame rail which gave the height automatically as it could not go lower.
Im not sure what they look like on a 3B.
I doubt you can get them new,I cut some out of a wreck with a chisel and grinder
You can also take some measurments from other BJ40 to check your work before you start.

welcome to the board. remember to try using the search function too.
searching 3b will get wayy to many hits though. So add words like conversion too.
Have you found a 3b? if you buy a parts truck, or donor rig, it might be easier.
But 3b 40 series in Canada are getting higher dollars it seems lately. And they are pretty rusty.
Other option in your 40 is a 4b-t cummins, 6.2l chev, and a few others.
Do lots of looking in here. You will find lots of info. But it will take time to sort thru it all.

I guess I'm looking for some pre-fab motor mounts
I have a complete BJ-60, rusted and smells worse than the barn it was in for nine years. Just got it back from Canada to Michigan. Now I'm looking for a donor body. Here's what I'm deciding between: my current 1988 4Runner (I love this truck), an FJ-60, or an FJ-40. In some ways I really like the idea of putting the 3B in my 4Runner, this truck has been great, I like the removable top, it can carry motorcycles or I can sleep in it. But theres a nice FJ 40 I can trade even for, so its a deffinate thought. Does anyone make pre-fab motor mounts for a 3B into the FJ-40?
Also I'm over here in the states so I can't compare it to a BJ-42.

Try an ad in the parts wanted.Must be few rusty BJ40 up in Canada that no one wants
For the 4runner, you might have to go with a solid axle conversion first. With a lift. A 3b is tall and very heavy.
With the prices of nice clean southern 60's I would go that route. But I do have a bias to a 60. They are nice classic looking trucks. Not all mall cruiser yet...
A 40 is nice too, but small. And you keep getting the "nice Jeep" comment. LOL
