I'm updating this ancient thread because I'm about to do something that is going to make a big difference in how much I enjoy this Land Cruiser.
Warmer weather is near and I plan to drive this truck quite a bit.
I remember reading threads years ago about seat mods to make the FJ45 more comfortable to drive. From memory, the recommendations were to raise the seat 1.5 to 2.0 inches.
The truck I bought already had that modification done. It had 2.5" spacers welded on to the bottom of all of the seat mounting points.
Today, I unbolted the front mounts on the driver's seat and wedged a 1.5" 2X4 under it to see if it made much difference.
Wow, with 4" spacers up front and 2.5" in the rear, I finally have a comfortable seating position. I am only 6' and about 200lb, but this truck was somewhat uncomfortable to drive before. I can't believe how much difference this made.
Of course, you couldn't do this if the hard top was on the truck. For this reason I don't ever plan to install the hard top. The back of the driver's seat is right up against the back of the cab in this position.
I'd rather drive it without the hard top in comfort than with the top on, in misery.
