A standard Chevelle frame will not fit an El Camino as it was based on the station wagon frame
same frame as a 70 chevelle. El Caminos and Station Wagons had the same frames. 4" longer than a Chevelle.
Yes... Sort of anyway. The Monte Carlo uses a 4 door Chevelle frame even though the Monte Carlo is a 2 door car. The 4 door frame is longer than the 2 door Chevelle frame. and the wheelbase is 4 inches longer. So if you have a Monte Carlo, a 4 door Chevelle frame will work. If you have a 4 door Chevelle, a Monte Carlo frame will work. If you have a 2 door Chevelle, then you will need to use a frame from ANY 2 door GM A body except for the Monte Carlo.... The Tempest/Lemans/GTO, Cutlass, Skylark, and Chevelle all used the same frames and are completely interchangeable.
Yes, '68-'72 El Caminos (Gen 3) are the same body from the firewall back. Frames are the same.
Yes.
there is no vin on the frame of a 67 chevelle.
no but a 66 chevelle frame will
measure the two wheelbases to find out, if they match then yes, if no you can extend or shorten the frame. 1964 Chevelle, 2 door or 4 door, hardtop or sedan frames interchange. Convertible will fit but the 2 door or 4 door, hardtop or sedan will not fit the convertible.
I have seen extended cab S-10 frames used, they are typically shortened a few inches because the wheelbase is slightly longer. I am planning on putting mine on a G-Body Frame (Malibu/ElCamino)
The 1970 chevelle body is mounted on top of a full frame the 1970 chevelle is not a unibody design like the camaro or nova
A frame from ANY '68-72 GM A body convertible will fit because they all use the same frame. I'd stick to the convertible frames because they are reinforced to deal with the lack of a permanent roof.
ANY '64-'67 GM A body frame from the same body type (2 door coupe, convertible, etc.) Now, you are MUCH better off sticking with the '66-'67 frames. Even though the earlier frames can be used, the '66-'67 frames are stronger.
