Lend me your experience

Yes, that's the one. Knock it in the end of the crank and you should be good to go. Just make sure the crank does have a deep enough hole. In '76, it should, but, check it anyway. If it isn't, there are a couple or remedies. Either drill the crank hole deeper (it doesn't need to be finished for a bushing however, just a rough hole to accept the transmission input shaft) or, lop off just enough of the trans input shaft to get the clearance.
