Project "Chihuahua" '65 Formula S Restoration "Estilo Mexicano"
Great job, don’t know how I had previously missed your build thread. Thanks for sharing your journey and the detailed write-ups.
I did notice something that I wanted to mention, that is that I am fairly certain your hinge retaining push nuts are reversed.
The prongs should be pointing out so they dig into the shaft, preventing them and in turn the hinges from sliding out.
Those often don’t work well after being compromised during removal. Your best bet is getting some new ones.
Also sometimes the shaft gets rounded off on the end and is either not long or square enough for the nit prongs to grab onto.
If this is your case, or you just want to ditch the factory design or having to buy new ones, you can just use standard washers held in by drilling a hole on the shaft for a cotter pin.
