That's BS... 1 out of 3 success rate and many of the successes aren't satisfied, how do they stay in business... Most that find they don't work, don't do what's needed to make them work, plain and simple! Welcome to that club.
What may work for a SS sprung car isn't necessarily going to work on a cal trac car.
The bars aren't some kind of magic bean.
Sorry, a car that run 10.60-10.70 and 60's in the mid 1.50's isn't a good working chassis. PERIOD.
Funny that the people at calvert were worthless not long ago.
