I thought that I'd post this on "B" Body Only, since this year is a "pre B" but I did not think it would go too far. The 8 3/4 rear on the '64 Chrysler have a tapered axle like the '64 "B" body? The car I'm looking at has a broken axle and will need a replacement.

Yes, it does have the tapered axle.

My experience has been that the most pain free and least expensive way for the 64 is to source a pair of used non-tapered shafts from a 65 to whenever C body. Loading, transporting and installing a complete rear isn't as much fun as it used to be. Just to find out the gears are whining, and the bearings are grinding>
Definitely do get them complete with known good bearings and all the shims.
If you have a sure grip rear in your 64 you will have to shorten/grind the 65/later shafts just a touch. Because the pre 65 sure grip has a slightly larger thrust block in the diff section.

Well you are close.
The sure grips from1958 and up all have the same center thrust block as a 1965 and newer open rear axle. 1.5"
It is the open differentials from 1958-1964 that have the narrow thrust block 1.25" so the axles are 1/8" longer per side.

After looking at my old nonreliable notes, I see that I had come to the conclusion that all "1964" and later axles are compatible and the change for the block width happened for the "1964" model year.
And the 63 and earlier open diffs used a "thicker" thrust block.
Yes, 1968 Monaco axles do fit my 1964 New Yorker. That one was an easy swap.
The 1966 New Port sure-grip diff/pumpkin I put into my 1963 New Yorker "open" diff housing "did" require trimming the original 1963 the tapered shafts.

I see.
I'm surprised that the 68 Monaco axles fit my 64 open.
