Torsion guys, I need your help!!!

[**grumpy**]

I am missing the block that the torsion adjustment bolt goes through on the bottom side by the bolt head.

Make any sense?

Is there a supplier that sells these parts? and are new bolts available?

Somewhere in the past 40 years, the block on the passengers side became missing. The only thing holding it all up is the bolt head

The little square block the bolt goes through is gone...........

Idea's?
