Ford 4100 tool purchase advice.

Which sockets or wrenches to buy?

Might seem like a strange question but I recently purchased a 1981 Ford 4100 and don't have sockets that seem to fit. I was recently trying to take the cap off the rear axle to add hydraulic fluid but didn't have the right size. I have a number of socket and wrench sets but mostly metric varying from 5mm to 24mm, but very few as large as some of the bolts/nuts on this tractor. I also have some SAE but only up to 3/4". I know that working on 80's US cars there were a mixture of metric and SAE fastners. I'm just wondering if this tractor has a mixture or if they are mostly SAE.

If there are only a few nuts/bolts > 3/4 maybe I could buy individual sockets rather than sets.

They are enturely SAE except maybe that plug for the rear end oil fill. I just use a crescent wrench for that.
You only need wrenches up to 15/16" to fix pretty much anything on that tractor. If you ever split it for a clutch you will need a
1 1/8" box end.

Thank you Ultradog.

I'll bet that plug is 15/16. I found a couple more sockets last night to try. Too big for a 7/8 and too small for 1". Looks like I might have to just fill some gaps in sizes.
