You had him shorten the control arms an inch? #-o
I truly hope this is a 1/4 mile car only. As in, the car is never taken on the streets for any reason whatsoever. Because just shortening the control arms an inch without regard to the suspension geometry is just, well, I can't even type anything on here that's appropriate.
Sounds like you need to talk to HemiDenny. K frame and suspension fabrication is not something to be taken lightly.
As for the original measurements, the LCA is 12.875" from the center of the torsion bar pivot to the center of the lower ball joint taper.
