This is one of those questions that was, I believe, at least partially answered by a link from the 62-65 tech page to The AutoHobby Digest Web Site. Unfortunately, the AutoHobby Digest site has gone bye-bye, for now at least. There was a detailed review of tapered axles on the AutoHobby Digest and, to the best of my failing memory, that article concluded you could not replace the '64 tapered axles with '65 flanged axles. Darned if I can recall why; maybe the lengths are incompatible. Perhaps someone else will recall. Also, there's a school of thought saying no need to replace the tapered unless they are busted. Here's something I dug up from 2006: "If you want to get rid of the tapered axles for some reason (they wont break by the way. i know cause i have tried!) get Moser or Bear or MW to make you a set of Street axles with the so called green bearings (non tapered self centering) and you are done, forever! i run the stock 63 tapered axles a 741 diff with a cone type posi in my 63 MW 426. I have a 3800 converter and 3:91 gears with 30.5 inch tall tires and i pound the living daylights out of it every time i go for a drive (when the wife isnt along ;>) since the year 2000. Been good so far. Don D." Now this opens up the debate about green axles: some report they have to use green bearings only on drag only cars. Others disagree. Let us know what you find out Akron Don. You may also want to read http://www.bigblockdart.com/techpages/875axle.shtml -- which is a copy & paste from AutoHobby Digest. Not the page I was thinking of, but may be helpful.
