Slow but steady progress.
The rear suspension is pretty much all back together now. Finished painting and reassembling the rear uprights on the weekend. The axles and track rod are in now. The design is a little different to how I first built it. I've added what I've learned building the CR bump steer kits and used the new clevises tied to the original chassis pickup points rather than tied to the point on the lower rear arm.
The axles are standard Commodore items so no need to make custom ones. I rifled through a bunch of different models at the wrecker and found a particular year that had the right length (VS I think).
Found I need to shorten up the sway bar links about 1/2" as there isn't enough clearance to the axles. Should be straight forward to do.
The next job is to sort out the rear brakes and then I can bolt the rear wheels on. Hooray!
