Well this body style is the Chrysler A Body Platform. Made from 1960-1976
1960-1962 is the first generation.. That's what we are dealing with here. - In the United States(possibly Canada as well) Sold / marketed as the Dodge Lancer, Plymouth Valiant.
Also known as the R and S series, it is quite popular in Australia and Argentina. (many of the restoration parts come from down under) as there are not generally parts available in the US unless it's used, Parts car, swap meet, interchanges with '63 to '66 Darts/ valiants or is NOS.
My Preference is the valiant, (I now have 2 of them) I don't care for the exterior styling of the Dodge Lancer (Produced 1961 and 1962 only ) quite as much but they are on the Same Unibody structure.
This of course is the Wagon is what you see in this post. I don't have production numbers but they are quite difficult to find now in a quasi presentable Condition.
I go to MoPar shows - Lots of Mopar shows.. rarely do you ever see these in real life at least in the PA / Ohio areas.
The Valiants were made in 2 door Sedan, 2 door hardtop, 4 door sedan (The most common to find now) 2 door hardtops and sedans are next on the hard to find list... then at the top of the list is the Wagons.
Various trim levels exist.. V100, V200, and then Signet Which is the top of the line in the Valiants.
I perfer the v100 as they are more austere and plain ( i own 2 v200's)
Things to look out for:
RUST - Windows were badly sealed from the factory causing Floor rust under the carpets especially in the front. These are all unibody.
Frame Rail Rust - really anywhere. Trunk floor extensions and of course lower quarter panels, rockers too. typical things that you look for in a 60 year car.
Rust in the pinchwelds under the window gaskets.
Power steering and AC were option many do not have those options... Many have no reverse lights.
I prefer the '62 Models as they share the k frame/ Engine mounts / front suspension /steering box with the Other '63-'66 Mopar A bodies... Reproduction parts in general and parts availability is better.
'60-'61 Have oddball fuel tanks and trunk floors that are unique to those years - Tanks are impossible to find, but can be remade by a good tank restorer such as moyers' gastank renu in youngwood PA
'62s can be retrofitted with the common '63-'66 Dart Vailant tanks easily.
These were never produced with 4 speeds; only the 3 speed (usually column shifted.. '60 and '61 were offered with a groovy floor shifter).... or the 904 pushbutton automatic.
My suggestion is find the best example you can find and afford if you choose to join me in the rabbit hole.
