I've been looking at pictures and trying to find information on the T49 and T67 experimental US tank destroyers:

The line I see repeated on the internet is that these were some sort of proto-hellcat designs.  The problem with this theory is that the running gear and suspension is clearly completely different.

 

As you can see, the T49 and T67 have a rear drive sprocket.  They also have independently suspended road wheels sprung by coil springs, rather like a merkava Mk III/IV.

 

The M18 had a front drive sprocket and torsion bar suspension, which IIRC shared parts with the M41 light tank:

So what's the story of these vehicles?

And so were on T20 prototype compared to T26E3/M26, yet none doubts T20 was a step in M26 development.

Well, they were not prototypes, just a development steps. Just like Soviet T-43 was a important development step toward T-54 even if it did not look anything like later.

M24. All M18 used here had running gear standardized with M24 which helped a lot with spares after '50s (a lot of countries had surplus M24 spares, few had M18 spares)

 

So what's the story of these vehicles?

Step in development of M18. Same idea of lightly armored fast vehicle, just did not work so development moved next phase, with larger vehicle, torsion bar suspension etc.

From the March-April 2002 issue of Armor Magazine.
