HELP! lol.
Getting ready to change all the fluids in my 70 cutlass supreme but, can't find the OE recommendations or the amounts. Can someone either tell me or shoot me in the right direction?

Do you have a copy of the Chassis Service Manual?
If not, you can join Wild About Cars and download a copy for free (the section you need is here), though I always like to have a real one to thumb through as well.

The OE recommendations will be somewhat obsolete by today’s standards.
Engine oil = Use something recommended for flat tappet engines such as Shell Rotella "T" I use 15W40 but they make 30, 10W30 & 10W40 too, I think. If you can’t find that several companies are specializing in the correct formula for flat tappet cams of yesterday’s engines or offer an additive. I use ProLong oil additive too. If you have a Shaffer oil distributor in your area use Shaffer. Best oil, grease, etc… I’ve ever used. Pricy though.
Auto Trans = Use Dex/Mercon II or III or Motor Craft Mercon V or TCIs Racing ATF (Jegs or Summit dot com)...good stuff!
Manual Trans grease =???
Brake fluid= Use Dot 3 standard brake fluid. Don’t use synthetic
Coolant = Use the off the shelf 50/50 pre-mixed. Don’t mix tap water with the concentrate only distilled or R.O. water if you choose that route.
Power Steering = Use a good quality off the shelf brand. You’ll need to flush it several times. Use a suction gun or disconnect the return side and run it into a jug for a complete drain.
Rear end juice= Use a good quality grease such as Valvoline 80/90. If it’s a posi put in the GM posi additive.
