Here is a picture of my 69 Firebird. I am running your split mono-leaf springs and Cal-tracs along with the rancho 9000 shocks that your tech department suggested.

This car is currently running a 455 Pontiac with Edelbrock Heads and intake and a Qjet carb. Driveline consists of a TH350 with an ATI 10 inch Converter and ATI hard parts and manual valve body connected to a 12 bolt with 4.10 gears, Moser axles and spool. With a 30x9x15 Hoosier rear radial, the car has had a current best ET of 11.44@ 118mph with a 1.54 60ft.

Your suspension components are a remarkable improvement for anyone that is wanting to get there cars full potential to the ground. Thanks again.
