The tensioner on my 77 engine is original and seems to be going out and I just wanted to try replacing it with the one from my dad's 83 engine that has been replaced at least once in the past 33 years. Anything special I need to do to just swap it over? I don't want to worry about changing the chain and guides yet cause I want to try something simple before tearing the engine apart. I have new gaskets for the thermostat housing, water pump, and tensioner, should there be anything I need to be aware of when trying to change it? Seems like it should be straight forward but I'm not to well versed on engine work.
