Any one know what kind of transmission fluid (4 speed std) and differential oil I should use in my truck? I found the quantities required but not the types.
I have included some pictures. I also included a picture of the ROBIN hydraulic ram system, even the pivot joints had ROBIN cast into them.

I used a hand held induction heater and was able to break the brake cables free, lots of cleaning and lubrication and they are working fine now. thank you for the help in sourcing new ones, which I would have had to purchase if I could not fix these ones.
