What are the differences? I thought '70 B & E were the same. Can I use a '71 E on a '69 B to get the internal sway bar?
I'd think you could if you use the matching lower control arms. Good upgrade too. I modified a GM sway bar for my 70 Charger. This was the cheapest way to get a 1.25 solid front sway bar. The 70 and later "through the K member" sway bar uses shorter sway bar levers, making them more effective. My bar has a "spring/resistance" rate almost triple of a stock .90 1969 sway bar. Of course you'll need a matching rear spring/sway bar rate to maintain balance.

I realize that, but I just noticed the connection on the LCA is closer to the pivot, thus reducing some of the effective rate at the wheel.

I think Frankenduster is on the right track here. But unfortunately, the inboard mount will really gain minimal results. The resolution in my mind is simply get a 1½" Poly mount, 1½" x 37.5" spline bar, and order the correct arms (1¼"x49spline) to attach to the LCA's.

I had the same issue trying to tell K-frames apart between B and E Body versions. The angle of the steering gear mount and the exact location of the driver side mount mount pad are the easiest indicators. I made a simple little paper template tool that I cut out and keep in my wallet to tell the difference. Hold the tool on the steering box mounts, line up the two bolt holes and the top tabs will line up for either the E or B body - Easy! This is better shown with a picture, here are two K-frames with the template held on them. E Body K-frame is shown on the left, B Body on the right.  I also attached a PDF version of the template, just print it out and cut out the template. Make sure the 1" box is really 1" and adjust the sizing with your graphics software if you need.

what year of b body is that thanks
The B-Body k-frame in the picture is a 1970 B Body, it is the one I am putting together for my '70 Coronet convertible. I've checked the template on B-Body K-frames from 66 through 70 and it works on all the ones I've tried. 66-68 B Body k-frames are easy to tell apart as the idler arm mount is single sided. It is the 69-72 B-body K-frames that are almost the same as 70-74 E Body versions that cause me trouble!
The E-Body was out of a '72 Cuda.
Hope that helps!
