Designed to replace your factory hinge trunnion with a stainless steel trunnion/delrin bearing on your tailgate. 
This reduces the friction while improving the opening and closing without the noise grind of those old factory original or replacement parts that will continue to rust.
These are designed to replace your exsiting hinge trunnion and it just takes a few minutes to replace. Its does require you to reuse your original mounting hardware bolts and lock-washers.
If you just purchase the trunnion ball & delrins for your 58-66 set, I would recommend that you powder coat your original hinge plates so further rusting will not occur.
We now offer stainless steel hinge plates as well. See our complete product line on the next page.
This item was the first year I produced.
You will need to reuse your original mounting hardware to mount to bed sides!
These are some example of the rusted items that create that aweful sound when opening and closing the tailgate.
