Hope you don't mind... might be a useful topic for us too. A question came up on another forum about rear sway bars. (sorry the edge is cut off).
Hey guys... I recently bought an ADDCO rear sway bar for the 65,, and was going to install it last night but ran into a problem... The sway bar they sent me looks like it's too wide to attach to the frame rails. On the early vans, the rear sway bar attaches along the rear axle, and the end links attach to the frame rails. Not the other way around like the mids. Here's picture from the installation instructions:
When I measured from one end link hole to the other on the sway bar, I got 39 1/2".. But when I measured from one frame rail to the other (center to center) I got about 36".
I called the tech support folks at ADDCO, and he said they've sold quite a few of these bars and it should be the right one.. But he agreed that you can't attach a 39 1/2" wide sway bar to a 36" wide frame...
Anyway,, what I'm hoping for,, is that someone with an early van could go out and measure the distance from the center of one frame rail to the center of the other, at a point about one foot behind the rear axle. ADDCO said they would have no problem bending the sway bar in some so I can install it,,, but I have to pay to ship it to them. If I find out that they goofed when they made this thing,, I'm calling them back and asking them where they got their info. I'd also like to know what year van you have, and whether it's a short or long wheelbase... Just in case they try to argue with me on this.
Thanks in advance.
