1972 CHEVELLE SS CUTLASS GTO SKYLARK REAR CONTROL ARMS

 

It's what I just installed on my '67 project, minus the swaybar. Of course, I haven't finished it, so I can't give any driving feedback. But the parts are quality-built and fit well...I was more than happy with them.

 

Doing a google search on PMT Fabrication didn't return too many results from forums.

So that tells me they're fairly newer, with not much feedback.
I'm a feedback kinda guy from Autocross and track racers.
.....no feedback = guinea pig. To me anyways.

Even someone that installs them, They'd have to do a track day IMHO to really know.
They do have the APPEARANCE of being similar to Hotchkis, UMI's, Spohn's, and BMR's suspension parts.

I was told those solid rear UCA's cause binding issues that the OEM one's do. Not much of an upgrade.
I got UMI's rotary joint UCA's instead so I could avoid those issues.
You'll have more flexibility in adjustments as well. Personally, I'd stick with the 4 I mentioned.
I have the Hotchkis TVS on my 78z.....big fat beefy bars.

 

I put a set of those on my 68 SS396 Velle last month. Decent pieces but no track time yet.

 

The lowers look just like the ones on my Hotchkis TVS kit.

OMG... I hope the rear end articulates and doesn't bind at all once I get it all together... don't want to disappoint some of the hardcore SC&C freaks over @ chevelles.com, LOL.
