Sway bar mounting holes on the lower control arm
 

So after spending several hours reading through a bunch of threads on here and a couple of other sites, I have not been able to find the dimensions for where to drill holes on the LCA to mount a factory 73-87 1 and 1/4 inch sway bar. I've noticed that most people use the LCAs from later model trucks when they do the disc brake swap, but I am still working with the 63 LCAs, so I don't have the holes. Does anyone know of or have a template on where to drill the holes in the LCA? Any sort of dimension to get me started would be greatly appreciated.

I'm really excited to get a sway bar on Frankentruck and carve some corners :metal:

Well If you install the frame mounts for the sway bar, you can put the control arm mounts on the sway bar and use that as a template. Not like your going to flex a sway bar much, only when turning.

Thanks, I didn't think about taking that route. I'm guessing the biggest thing is just mocking everything up a few times and seeing where it all falls in to place?

Also is there a certain amount of the bar that is supposed to stick out the back of the LCA mount?

Yes the bar sticks out past the LCA sway bar brackets bushing, can take a photo of 65 C10, all the C20s are apart. Just from memory some where around 1/2” or a little more. For drilling your LCA holes, have Truck at ride height may help.

The photos below are from a 66’ C20 Truck, will get some for a C10.
