Swapping axles & complete rear-end assemblies may not be that easy. From our friend Burt at: http://www.allpar.com/history/mopar/300-letters.html The 1963 car was styled by Cliff Voss, and the classic expensive look of the new sheet metal met with a lot of Corporate enthusiasm at style approval. I was also impressed by the expensive character of the style but in my opinion the car needed more rear track to get the tires and wheels out closer to the quarter panel surfaces. I was unable to sell top management on the expense of making this track change to what was supposed to be a carryover platform. Nor could I get the support of engineering and manufacturing management to this change, which required changing the rear axle, rear suspension, and rear floor pan. It meant more work for them. Whenever I see a 1963 or 1964 Chrysler I think, “if only I could have . . .” A little table:
In addition to chassis design, tread (or track) specification can be affected by brake drum size, wheel offset and tire size. It appears Chrysler popped for a wider rear end in 1965. A similar table of flange-to-flange dimensions for the differential assembly would tell the tale more completely. As a point of reference, the 1969 “Wide Track “ Pontiac$ (and 2016 Chrysler 300’s) had F&R track of 63” & 64” respectively. ’69 Cadillacs had 63” both ends. ’70 Imperial: 62.4/61.1.

The folks that sell the disc brake conversions hopefully have all this figured out. Rich Barber Brentwood, CA From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of John Nowosacki jsnowosacki@xxxxxxxxx [Chrysler300] might be blasphemy to some, but it could be time to start listing what rear axles from later models swap in to our old Brutes. Time marches on. Hard to stomach the fact that my 57C is a 59 year old car now. I feel like I've become one of the Model A guys I used to stare at in wonder in my youth. Who would want a 60 year old car, anyway? My 'old' cars were only 10 or 15 years old when I started appreciating and playing with them. No where near as many 57 Chryslers were built as Model A's, so I don't expect anywhere near the availability of remanufactured parts to ever be available. Would some late 70's or even 80's rear axles (perhaps with disc brakes?) from a large Chrysler or even a Dodge truck swap in? Even fans and owners of letter cars get updated hips, shoulders, and knees when the original equipment wears out. I'm not talking the full resto-mod movement with Hotchkiss suspension/frame and 6.4L modern Hemi drivetrain swaps from Magnums and newer 300's and all, just newer parts that might have less metal fatigue and more years left in them? It saddens me when I see some of my 'old car buddies' cashing out of their classic cars and running off to buy a retro-look Mustang/Challenger/Camaro to bring to the cruise nights, but they seem to be happy to have relatively 'trouble free' motoring for the rest of their lives, as their cars will certainly outlive them. I await a wide range of replies. ;-) On Fri, May 27, 2016 at 3:20 PM, 'Mark Lindahl' mplindahl@xxxxxxxxxxxxx [Chrysler300] <Chrysler300-noreply@xxxxxxxxxxxxxxx> wrote:
