Hello everybody
I'm working on a 1936 120 for a family friend today and want to change the fluid in the rear end, but I cant seem to find out what kind of oil is best to use
I got straight 30 weight for the engine and 90 for the trans
I was going to order 600 gear oil which is what I use in the rear of my model T but figured it might be wise to ask here first
thanks
