NEW PST pivot shaft bolt sheared off. Can't get LCA out.

Disassembly time and a new pin and bushing if you don't have poly in it, that sucks.
That always concerned me about the greaseable pins.

Take the retainer clip out for the T bar and it might just slide back without the tool.
You can also use a pry bar and force the lower arm back instead of grabbing the bar itself.
