The major thing is that I am not very good with fabrication, I actually never even tried to weld so I needed some bolt-on conversion. 1HD-FTE is just like that, the engine mounts are there, and the auto transmission (a442f) just bolts directly to the same place as a343f which was there...
I am an average idiot and I did the 1fz-fe to 1hd-fte conversion by myself in the parking lot.
Below are some pro points:
* there is no need for fabrication at all, the engine and 4-speed auto just bolt to the chassis
* this conversion is well supported and documented by the land cruiser...
