With all this said. . .what is going to be the best route to finding out which u-joints I would need to buy to replace the ones I have? Seeing as I am not 100% sure on the age of rear differential or what it came out of. With the transmission I am more positive that it is a 74 th-400 as I figure it was mated with the engine.
Do the u-joints have information stamped on them I could use to match up to a new one?
Also, I know they make different kinds of u-joints but I want to choose the right ones for my application. The car is a street/strip car. I take it to cruise nights, shows, to the local hangouts and to the strip. So in my application is it better to get the ones with the grease fittings or a sealed unit?
Some of the part stores are awful here where I live. They cant search anything if its not a stock item.
