On the Carrier learning curve

[meduffer]

Hi,

My son helped me set up a decent molasses de-rusting (chooching) tank made from an IBC plastic tote. It's parked in the back yard under a tree that has a very convenient limb for the chain hoist. Forfunately I haven't received any "lingering stench" complaints from the adjoining neighbours. This first batch we're soaking comprises of half of the seized track and a raft of other rusted pieces. I'm very interested in seeing the results. One of the pieces is this 2" angle. It has the Ford stamp but the part number is obscured. Can someone identify it for me?

Thanks muchly,
Mike
