I have Magnum Force on three cars, love them. I have the standard one, the single adjustable and the double adjustable. 10k miles on pothole riddled California roads in 5 years one the Cuda. No wear and didn't squeak a bit. They might be back ordered for the meantime as they had a new shop built and have been transferring over.

I have a set of Firm Feels on my 1970 'Cuda. No issues and it does seem to handle a bit better with the added caster they allow.

I used the Firm Feel tubular uppers on my 70 Sport Satellite . . . went with the "standard" rubber bushings - no squeek. Also, because I like to drive the car, and never know when you can encounter "weather" . . . I prefer the rubber bushings, over the hiem joints. . .
just my 2 cents
Cheers,
Mark The non adjustable magnum force arms are rubber bushed, not that anything wrong with the billet ones.

If budget matters, you can shorter the rear arm on each side of your original ones 1/4" and with the offset problem solver bushings you will get all the adjustment you could possibly need. It used to be called the Ford mod or the Ford cut which is where I first heard of it years ago.  I have done this to all of my Mopars for many years. It is cheap and effective. My alignment guy always has plenty of room to get it where it needs to be.
Master, again and still

No opinion on the arms, but what I can say is stay away from poly control arm bushings. I've used poly bushing on almost everything and never had squeaks. Ordered them on the tubular arms and the squeaks are driving me nuts.

Comparing the MF curved arms va the straight arms, seems to me the straight ones are stronger.
Think compression & extension forces vs bending an arc.
Dave's comment on modding the OEM arms has merit: my Duster (sig pic) had the front leg widened about that amount by Jack Arnew back in the day.
Car goes straight as a string @ 130 at the track, runs about 7 deg pos caster.
Wheels remain vertical during wheelstands with no bump steer when it sets down.
Only side-effect is it self-centers aggressively, don't have your hand between the steering wheel spokes when it centers.
Depending on the combo, 3.5-5.0 works well on the street.
. Not sure if this is of any concern, but the MF arms are made with chromoly tubing and US sourced. I know most other brands use mild steel tubing. I’ve never had an issue with strength and the only two times I ever seen them bent in 15 years was due to severe accident impact. If fact, when the guys 1968 Barracuda got clipped and hit the side roadway, it was still attached to the spindle when the frontend came off the car.
