I hope I won't get flamed for this, but I'm out of options...


would a 2nd or 3rd gen Camaro upper control arm fit on a F/J/M-body?

how bout an A-body UCA??

You should be able to find one here used for pretty cheap. People used the spindles for disk brake conversions and they have to break the upper control arm ball joint in the process.

How could a Camaro arm work on a Mopar ? They are a totally different suspension design and everything else...

As mentioned, try a wanted add here or just look in the classifieds section and bet you'll be able to come up with something.

I know the B-body guys have been using our spindles for awhile now for the cheap disk brake swap.


I've actually got a plan in the works to use the new drop spindle that Magnumforce is making that's is based on the B+/F/J/M/ spindle

I am gonna use it on an M-body.

So I'm looking for an adjustable upper control arm that'll leave me room for a coilover later on.

(I've got a bet with a friend in a Mustang riding on this, the thing's gotta get around Road Atlanta)

well, I was looking at one of the control arms that Howe Racing makes for the Camaro and noticed it looked a bit close to the M-'s control arm.

Sure, it could be adapted. But for the time, effort, and cost of making a Howe arm fit, it would be easier to just go to the local pick a part and get the correct arm for $10.

Oz, FJM upper arms are more like a chevy arm than traditional mopar arms. They have a cross shaft and use shims for alignment.

What about ball joint location though ? I was thinking that... Guess ball joint taper would be easy enough to machine up if needed be

I'm still needing the adjustability though.

here's one of the A-arms in question:


and the other:


both are for oval track use, but I love the amount of adjustability the first one has.

Might be better off with one of these that comes with the cross shaft installed. Without comparing the chevy against the mopar, you may use up all the adjustment to get the caster set up, plus the cross shaft bolt pattersn and width are most likely not going to match either. But, your dime and your time.

If you going to convert to coil overs later, don't forget you'll need to add a strut rod or some other triangulation device to the lower control arm as well.

yeah, the strut rod is in the works too.

ok, another question inside this question.

The car's gonna be going drifting too, so
I'm needing to radically increase the amount of steering angle I have.

I'm gonna move the tie rod connection point on the knuckle closer to the pivoting axis,

like this:---->


and, granted it's on another car, another couple examples:




can ya'll think of anything else I can do for more steering angle?



Yes, I'm starting to think I'm nuts for attempting this.

Yes, buy a www.firmfeel.com quick ratio pitman arm. And C-body idler. Might put the center link in a slightly different location, but easier and stonger than then welded steering arm. Something to try, you are in the realm of heavy mods so no guarantees. Both longer pitman and shorter steering arm will change bump steer and akermann. Probably not a deal breaker with a drift car.

Steering angle is going to be limited by rim offset and tire to frame clearance I would think.

oh, I forgot to say I've been talking to Firm Feel about the spindle mods, They think it should work.

I was thinking of running the 17x8 Cragar 8-hole rims, so it should have some more offset than the stock steelies
