hottarod 5pts With the TCP export brace and monte carlo bar, the only way to properly install these is to have some specific measurements to make sure the shock towers are positioned like they should be. I have not been able to find any official measurements anywhere. I did find a few observed measurements for my car which is a 65 fastback. The inside bolt to inside bolt of the shock mounts is said to be 30 1/2". Mine is a bit less than that with a jack on the cross member and the wheels off the ground. I have seen some people measure every car they have which can be a few and list various numbers. Back of radiator support to front lip of cowl was listed at 39 7/16 inches. Inside bolt head to inside bolt head of the top front bolts(just forward of the shock towers) for the coil spring covers was listed at 42 inches. Are these good measurements to go by?
