Guide Me Through Manual Steering

Hi everyone.
Working on a 73 duster drag car. It looks like the previous owner modified the k frame and is running a manual rack and pinion. I found the part number on the rack and its in the pic below. The rack is ran through the front where the sway bar would go. I contacted trw and they dont have any info on this part number.

Can anyone help me identify what rack and pinion this is. I have heard of people using pinto and mustang 2 racks but I have no clue how to identify if this is one of them. Also, the steering column is there a place a part number will be located. Wondering what vehicle that came out of too.

Thanks

pics of the entire set up? Did they just slap a rack in there, or relocate to front steer? Either way, the geometry is likely to be off. Pics will help
