Well, I bit the bullet and placed my order.....

When I bought my Alter-k-tion for my E-body Bill did not have the Street Lynx rear system out yet but he was selling Ride Tech triangulated 4 link. Ride Tech was called Air Ride Technologies in those days and only had air bags. You could order the system through Bill without the airbags and he would add in the same coil overs as the Alter-k. I have QA1 coil overs.
That car is mothballed while I work on my A-bodies and D100.
I can attest to the Alter-k-tion and a triangulated 4 link handling like a whole different car. That thing handled like it was on rails for the couple of years I had it streetable. I need to get the shocks rebuild and freshen up the 408.
