The underbody of my land Cruiser has definitely seen better days and I’m not surprised to see the fixing point rot away. In some other Country’s the Land Cruiser 100 is equipped with a auxiliary tank and the same fixing points are used. The bolt holes are unusable which ment I had to cut the rotten material away.
This must be the cheapest available weld-on nut what Toyota’s money could buy. I’m not surprised the thread was not existent.
To make a strong connection I used a mild steel box section which I have welded a nut inside and bolted on to the rear underfloor panel reinforcement. This should last a long time.
Everything is painted with chassis Lack, connected and bolted up. Before fitting the tank I sprayed on some underbody and cavity wax.
Next step is fitting the tank.
