Use the "search" function and you'll find some responses to an almost identical question a few days ago. In a nutshell:

I'd avoid 10W-40 oil, if your engine is in good shape and you live in a reasonable climate, 10W-30 would be a good choice, 15W-40 a better choice.

Unless you're going to completely flush the brake system and change over all the rubber components, you should stick to the same brake fluid that was in it, as modern silicone type which some people prefer isn't compatible with the traditional types. If your system wasn't converted to silicone, DOT-3 is probably what is already in it.

You pay more for coolant that's used full strength because it's already diluted. Matter of cost whether to use it or the convention (green) stuff, just read the chart for the protection you need for your cold weather, the additive packages for corrosion control and pretty much the same. Don't use the modern "red" stuff.

I guess you transmission is Ultramatic? If so I'd use Type F or FA; if it's stick, SAE 85W-140 HP gear oil, and the same stuff in the rear axle and steering gear box.
