yes, but you will learn less that way, and you will miss out on the whole experience of fixing it.
If all you want to do is drive it with zero problems and have it just work, then, well, no. Its 50+ years old it will break and you will need to fix it. Also, throwing parts at it could take longer than finding the EXACT problem and just buying the correct part or finding that it was something stupid and fixing it in 2 seconds.
Sure, you could buy all the things you have not replaced yet, then you will have spent more money, and time than what was needed.
But thats just me.
