Can't tell anything that it was hooked too. Don't see anything that would say it was a scrub brake. My guess was maybe it was used In place of of a hand brake to operate the front drum. It does have cable attached to it like it would be wired for throttle or brake. There is also a 5 cent kick stand welded to the frame smh
Making some headway though. Should have her up and running by Thursday. I am eating on my torque converter. Here's a pic after today. Made the seat myself. First time upholstering and I got materials for free. Main plan is I need it rolling and running this weekend then will pick at different things.
