I was looking at the shifter from under the 72 and the 73. I seem to be missing a spring on the 72, the spring directly under the shifter. I guess it might help to have that one on as well? Looks like the pin is in place but did not see it all the way through. Is there a way to work on all this with out removing my boot, is original and in very good condition. I am still fairly new at working on my GT and have the factory book but does not always say the best way to go at a repair. (one of the many reasons I love this site.) Thanks
