Greeting Gentlemen, my first post here and a new owner of a 64 Riviera. I've been lurking for a week or so and reading the vast amount of knowledge that is being shared here. My 64 can use a little help the suspension area. The front has new springs and rubber, but the rear is still original. The rear springs are sagging, track arm need new bushing along with the control arm bushings. I've read about Tom T. (telriv) sway bars and faster ratio steering box and find them interesting and would like to know how to pursue getting them for my 64. In addition, the rear springs need to be replaced, and I was wondering if the GS springs would be a better solution given that Tom's sway bar raises the rear a half inch or so. Thanks in advance for any advice you can share with me.
