Some updates- Camaro rear sway bar...
Once the rear suspension was all together I tackled the rear sway bar using the junkyard 82-92 F-body 7/8" bar. From what I can tell this is the same size dia. as the largest factory stock G-body rear bar, the advantage being it will be attached to the frame rather than to the lower control arms.
I thought for sure this was going to be a pain and require a bunch of fab work but I found just the opposite. I ordered an extra set of FRONT g-body sway bar links, guessing they'd be just about the right length. At my car's actual lowered ride height they are the perfect length.
With a mock up of everything bolted together I found it fit right up into the frame. Only mod needed was shaving down the side of the brackets for shock clearance (green arrow). Notice how they are positioned here, they need to go into the car like this, right and left accordingly.
With everything mocked in place I marked the spot to drill the holes using the existing holes in the brackets. Then I drilled a pilot hole through both sides of the frame rail with a 3/16ths bit. On the outer side I drilled a 7/8" hole with a hole saw to allow access to the bolt. I then drilled the inner hole using a 3/8" bit. A 3/8" x 1" bolt and nylon lock nut finished the bracket bolt in. The outer holes are plugged off using plastic hole caps from Home Depot. Pretty simple actually, the hardest part was lining up the bracket at the right angle.
In this final photo, (sorry it's a little dark) you can see where the bracket bolts are (green arrow) and overall fitment. Notice the angle of the bar to the link is off (red arrow). This is the only disadvantage to using the upside-down F-body bar, the angle on the ends is off. With the suspension dropped about another 1.5" or so, which is estimated ride height for my car, it's a lot closer to the right angle. This might be way off with a car at close to stock ride height though, you might be able to fix that with longer end links but I'm not sure how that may affect stability of the bar.
The Camaro poly bushings and brackets that mount to the rear were in good shape so I just re-used them. The Camaro axle housing is the same or close to the g-body so it was a direct fit. With the 9" the axle housing is a lot larger, so when I get to installing it I'll use some 3" muffler clamps and fab up mounting brackets.
So here's the end result- sway bar and brackets from the wrecking yard- $15, end links with poly bushings from Summit- $4.99 ea., and bolts, nuts, and washers about $3, so for less than $30 I got it all set up. With the bar flipped I don't know how that may affect handling or functionality of the bar, however as I mentioned previously having it backwards like this is common on trucks so the assumption is it must work fine. Track time will be the ultimate test to see if it will be just as good as an aftermarket set-up that runs 4X as much $. At the very least it will be better than the factory bar that bolts to the control arms and it's keeping me in line with building on a budget. More coming...
