Help in Identifying this Steering Box (1 Viewer)

[Diesel Wannabe]

I bought a rolling chassis from a '79 BJ40. It has this steering box installed. Can anyone identify what this came from (the recent owner didn't know what this box is and where it might have come from? This looks like the one on my uncle's FJ62, but the tapered hole for the relay rod end seems to be between the sizes of the FJ40 and the later FJ60/62. Appreciate any help.

Casting numbers that I see are:

1F20343 (near adjustment screw)

60020
5C0

80 series?

the curved steering arm is throwing me off, do 80 series have a curved arm?
what is the bolt pattern on the box? is it square? or a parrallel a gram?

It appears to be an 80 box based on the description and images here.

Thanks Bryon and 3 Puppies. It does look like the 80 box. I'm confused because of the size of the tapered hole - it's too small for the bj70 relay rod end that I have. I'll try and check the specs on an 80 end and see if I can make that work...
