It looks like an update to provide better clamping force for the nuts/bolts in the slots. You can see it in the pic of the assembled unit on top of the slotted area.
It’s a plate to fix the side to side positioning. I always figured they were left slotted do compensate to some degree for a 40s frame flex.

My bet is they are giving rubber cushions that are way too rubbery/allow way too much movement, so they are eliminating the movement with the bracket in yellow.

Just wanted to give an update. Thanks again for everyone’s input it really provided me with ideas and options.

I had time last weekend and Monday to visit the local pick n pull junkyard. I ended up getting brackets from different vehicles and a different pump. Took it home and used the one that worked best with the least amount of effort to fab up.

This is what I came up with and seems to work very well.

Drove it around the neighborhood and everything felt nice and tight. When I pulled it in the garage and kept it idling to check for leaks and any other issues, everything looked nice and tight but I have a leak that is coming from the front of the gear box input shaft area. 👎

The leak seems pretty bad. It may be a bad seal. Are the seals easy to replace on these old Saginaw boxes? Is it worth replacing or better to order a new one?

I’ve never worked on one of these boxes. Since your box is nice and tight, I’d be inclined to replace the seal. I’ve read that cheaper rebuilt boxes are somewhat of a crap shoot. They may have more play, and trying to get a four turn lock to lock box often requires ordering multiple in and picking the one that’s right. Some mudders report getting used to quick ratio boxes. Having just done a P/S conversion, I’d say you can’t go wrong with a 4.25 turn box… and you may hate a 2.5 turn one.

I’m not sure which box I have. I’m finishing the job that the PO started. I get 3 and a half turns lock to lock.
Here’s a picture of the installed box. Anyone know of which seal kit to use?

Thanks for the link. I read it 3x and still not convinced which direction I’m going to take yet but I’m partial to buying a new one since it may be the easiest forward path.
This FJ40 project is a lot more work and time than I anticipated. May have to hire out to finish the remaining work since my FZJ80 is not getting any attention. 😂

Looks like a 4 bolt box. I can understand how much time projects like this can eat up. I can completely understand buying the new box.

Recently I bought a rebuilt power steering pump rather than test another spare pump to see if it wasn't noisy and worked well. It was well worth the $35 to only have to remove and replace it.

This might help identify your box:

BTW, the pressed on pulley can be pushed on further or pulled out to adjust the alignment if it is off.
