Rear spindles locked in place

The rear spindles, are actually front spindles from the late model Cadillac. this means, they are intened to steer. in order to use them in the rea, we needed to make a third link. It is important to figure roll center, and work out bumpsteer. most times, bumpsteer usually effects the front., but with independant rear suspension, it is also a factor. this Third link, has been sized a positioned to have zero bumpsteer.
