64 to 66 Frame Differences?
Is their a better short bed frame to use for a 64 to 66' performance driver? Maybe a few trips down the 1/4 mile too. Some of my research found that 65 - 66 frames have improved mounting locations for certain rear suspension components, like pan hard bar.
Help on performance frame difference would be greatly appreciated. Les |

Re: 64 to 66 Frame Differences?
There's really no differences in the '63-'66 frames as far as strength goes or overall design. The only difference in the panhard bar mount is the angle of the '64-'64 versus the '65-'66

It also means that you can actually weld to these frame without the same problems (weakening) that you'll see with the more modern steel frames. Some folks have chosen to box or brace the frame (usually along with other mods, like a frame notch or coilovers etc)

Thanks for info/ suggestions. Best way to check bare frame to make sure straight? Cross measurement between body mount locations. Les |

Re: 64 to 66 Frame Differences?
Get it on a smooth flat concrete floor and drop a plumb bob from the outer most corners and make some points on the floor. Then you can diagonal measure and see where it's at. You can check all sorts of things using the plumb bob method.

Re: 64 to 66 Frame Differences?
Easiest way imo would be to level it on some stands, then measure a series of recorded points (so corner to corner etc). As long as its pretty close and level, all the rest should line up too. BUT don't be surprised if even with a straight frame, you have a crossbrace that looks crooked. I swear some guys use to "eye up" the holes at the factory.

Re: 64 to 66 Frame Differences?
Captainfab, Do you know how much changed in just the frame rails and main cross members between 63-72?

Re: 64 to 66 Frame Differences?
The differences between the '63-'66 and '67-'72 frames are 1) The front frame horns for the bumper. 2) The position of the radiator support mounts 3) The very front crossmember. It is the radiator support on the '63-'66 and on the '67-'72 it is farther back and does not support anything except for a brakeline. 4) the position of the rear cab mount brackets.
Otherwise they are pretty much the same.

Re: 64 to 66 Frame Differences?
Thanks for the info, How far different is the rear cab mount? And c10, c20 are the same frame, c30 is when it gets taller? truth to that?
And now that I look at you location. You sir are where I originated from. Grandpa grew up there and most of my family is still there but slowly moving south. |

Re: 64 to 66 Frame Differences?
I don't recall the exact measurement but I believe it is a height difference between the top of the frame and the mount bracket. I would have to measure each one to get an exact difference for you.
Yes the C10 and C20 frames are basically the same. There are minor differences such as I believe the steel is slightly thicker and there are forward braces from the trailing arm crossmember to the frame rails. The C30 Dually frames are a bit different, but I do not know about the C30 single wheel frames. I have not seen or had one of those. So you are originally from CDA?
