If its through the k member thats a 68-69 k member and control arms. 70 bars don't have that sort of 'W' shape more of a '\_/' and mount more forward on the k member. I don't have a skid plate on mine but have the Firm Feel bars front and rear with no fitment issues. If you are still bumping you could try spacing down the sway bar brackets and different length end links. 
no you have it backwards , 70/up is thru the K , 69 bown is mounted to the front of the K .

Uhhh..........
I thought that the 69 and back B bodies had the front sway bars mounted on the OUTSIDE of the K member, on the leading edges close to the fan shroud.
I have a 70 Charger, originally a 318 car. NO skidplate. In 2001 I modified an 1 1/4 front sway bar from a 78 Chevy one ton truck. The contours were very close to the stock bar. Later my friend did the same on his 71 Challenger. I eventually went with an Addco 1 1/8 front bar and a 7/8 rear bar. T bars are 1.0 and I have the xhd leaf springs from MP. The car oversteers at times even without throttle, and I am actually considering switching the rear bar to a 3/4 with rubber bushings to soften the roll couple distribution. Sure its FUN to kick the tail out at will, but I certainly dont need a spinout on the freeway when I try to avoid some 87 year old with cataracts driving 48 mph.

I noticed your car is a Charger 500 model...so your K-member would not have come with the skid plate from the factory like the R/T models...that is the difference as the sway bar feeds between the skid plate and K-member on 70 Charger RT models.

Interesting...oversteer with the 7/8 rear sway bar and 1 1/8 front even without throttle....I will then also go with a 3/4 rear as well to start.

I even have staggered tire sizes. 275 40 18 in front and 295 45 18 out back.
Years ago I was a Camaro guy. I experimented with all sorts of sway bar and spring combos. The junkyards were ripe with parts to try out and I took full advantage. I had a 76 Camaro with a 350, 4 speed and a 3.42 posi diff. That car handled best with an 1 1/4 front bar, Olds station wagon DIESEL coils and stock multi leaf springs with a 7/8 rear bar. When I bought the Charger, I thought that sway bar science was based on a ratio of front to rear . The mid 70s Z28s had 1 1/8 front bars and 5/8 rear. The Trans Am cars got the bigger set, 1 1/4 and 7/8.
Tuning the Mopar Torsion bar suspension cars uses the same principal.
STOCK 7/8 Front bar....NO rear bar.
Aftermarket 1 1/8 front bar....3/4 rear bar.
The higher rate rear springs I have sort of skews the numbers a little. My trial and error tactics at work! My thinking was that the car weighs about the same as the Camaro, so it needed a big rear bar. The Charger has an aluminum headed 440 vs an iron 350 the Camaro had. Truth be told, the 2 cars are apples and oranges, but I really wanted to make the Charger handle as good as possible. The sad thing is, the car turned out nicer than I expected and I have been too much of a 'fraidy cat to let it really hang out. Sure, I enjoy burnouts and a 100 mph blast occaisionaly, but I'm nervous about power drifting through turns! All this stuff is hypothetical of course. I always obey the law.

Yes and Yes.
If the two bars are identical in diameter and arm length, then they will be identical in rate. If you had the chevy truck bar cut down to mimic the identical dimensions of the charger bar, then they will be very close to the same rate. Since I've never seen your set up, I can't comment on how identical they may be, but it sounds as if you did the work to emmulate the original set up rather than just stick the bar under the car. The assumption I made is that you just bolted the truck bar up under there without changing anything. However, you still don't have enough front roll couple. Bigger t-bars or a softer rear set up will be require to return to neuteral.
On the rear bar, there are two styles readily available; the OEM style, frame mount 3/4" bar and the aftermarket, under axle 7/8",15/16" and 1" style. The two styles are not identical as they differ greatly in mounting methods. As a result, the larger, under axle bars have much longer lever arms than the smaller diameter, shorter arm length factory style bars. You didn't mention which rear bar you have exactly, but again, my assumption, is that with a 7/8" bar, it is the under axle style. If you indeed have a frame mounted, OEM style 7/8" bar, then it is a whole 'nuther ball game. In that instance, the change to 3/4" will yield a very large change.

Yeah...I had purchased a Hotchkis front sway bar a couple of years ago that didnt work for my car...I had thought about cutting the weld on the plate but really didnt want to mess with it so I sent it back. I was under the impression that it should have fit without having to do so at the time.
BlakCharger440,
There are so many options on vintage cars that we are not always able to accommodate every feature. We do address the skid plate in the instructions for out E-body (and 70 B-body) bar. Unfortunately, the install does require temporarily removing the skid plate.
--------------
Here's the step from the instructions:
7F. Cut Skid Plate
If your K-frame has a skid plate you will need to cut the front welds that attach the plate to the k-frame. This will allow you to carefully bend the skid plate downward to allow the new bar to go in. Use a cut-off wheel or grinder to cut the welds. You will be re-bending and rewelding the plate back to its original position later in this installation.

If you’re within driving distance of Las Vegas, we’d love to see your RT
out at MATS in April!

DOH! Sway bar dyslexia strikes again. I've never actually owned a 68-69 with sway bars before.
