1973 Ford 3500 - where to add hydraulic fluid?!

[KarlFord]

I just got a 1973 Ford 3500 backhoe, and need to add some hydraulic fluid. I've been searching and can't figure out where to add the hydraulic fluid! Can anyone direct me to where to do this?

Thanks!!!

The hydraulic fill should be on the top of the left side loader post.
Same as my 1970 Ford 3400 which just got picked up by it's new owner today.
