Great looking truck and all the better with so many good memories. Do yourself a big favor and buy an official 1969 Chevrolet Truck Shop Manual. You will find lube information and thousands of other useful things to help you get to know your truck better. Just Google 1969 Chevrolet Truck Shop Manual and several sources to buy a manual will come up. The one I looked at cost $30. You said you changed the oil. Be sure to change the trans and rear end fluids too if you haven't already done it. Have fun!
