Just curious, are the Volare/Aspen, Demon/Duster, newer Dart/Valiant bodies the same thing with just a different name? Just wondered, seemed to me to look a lot alike. Whenever I hear Dart/Valiant, I tend to think of like the mid/late '60s.

 

There were some serious changes in the Volare line.

But there are MANY similarities (all of which I cannot name) between the 67-8-9 A bodies and the 70/ later ones.

For example, I have a V8, disk brake setup out of a junked '74 which will bolt right under my 67.

Torsion bars, springs, suspension parts are "somewhat" the same---there was a change in spindles/ lower ball joints between disk/ drum brakes. Rear suspension/ axles interchange

Minor difference in the SB engines is the change in the water pump from drivers side lower outlet to the later pass side. What this means is, if you are putting a late engine in an early body, you have to either use the late water pump (and timing marks) AND change the radiator lower outlet, or else figure a way to change or "make" early pass. side timing marks, and use the early water pump/ radiator setup. "Minor problem"

727 TF is longer than 904, and uses different slip yoke splines, so if you drop a 727 Torqueflite in place of a 904, you'll have to make a new driveshaft/ shorten yours.

I've been told that the 70/ later doors will actually bolt up to the 67-69 series, but of course the windows are different --and no vent windows.

It would be better if you asked a specific question, rather than rack our brains for the exceptions.

 

Sorry about that. Meant mainly to the body, all look very similar to me. More like a model year change than being actually a totally different body.

 

Dart Duster Valliant Barracuda (first generation) Demon and Dart sport, are all A bodies. The Volare' and the Aspen are F bodies.

 

I can cover the Volare/Aspen....1976-1980 F-Bodys...were known to alot of people as rust buckets. They had crappy horsepower low CR motors...started with a little smog crap then ended up with alot of smog crap. Some of them came with an 833/O overdrive tranny such as the one in my car. The most common motor in them was the 225 /6. Go to the F-Body section and look at the Dealer Brouchures.

 

Your body style Dart is what first comes to my little mind when I hear Dart/Valiant. The newer body styles are the ones I was more curious about. Saw an article some time ago in Hot Rod where they were building one & just thought it looked to me a lot like the Aspen/Volare body style which I always thought bore a strong resemblance to the Demon/Duster body style. Not trying to say they are the same thing, just always thought they looked fairly similar.

 

looked fairly similar, basic size and shape.

Yeah they looked similar , basic size and shape. They even used the Duster name on some Volare models. (79&80?)
However thay were completely different. The sub frame used transverse mounted torsion bars and are the same as a Diplomat and other such cars of the 80's. Nothing will inter-change from the older
A-bodies to the later F-bodies. Well, the wheels on later 72 & up (I think) A-bodies will fit the F-bodies. Earlier A bodies had a smaller bolt pattern.

 

I think all A-bodies had the 4' pattern up to '76. I don't recall any having the larger pattern, just a different disc brake setup. My '74 duster had the 4" pattern. As for the later Volare (Duster)/Aspen, totally different animal, just the same basic style.

 

MR340 is correct on the bolt circle...A bodies finished in 1976 with 4" bolt circle. F-Bodys started at 4.5" bolt circle in 1976 and finished in 1980 with the same size. We is the tire size I can run on my F-body with no wheel tubbing.

 

next to nothing is the same body wise some small trinkets but thats it the A body platfrom and F body platfrom is like dogs and cats the 1977 volare used the duster nameplate for a minute but that was the end of the A body platfrom in the U.S
