Is there a good reason for needing the extra adjustment correction? Those shafts are generally used to compensate for a sagged front crossmember, and it's a lot more effective to have a frame shop stretch the crossmember back into position. I've done this several times when I was teaching alignment procedures in three public schools.

I do have threads left on the drivers side cross shaft bolts. Its 'one' bolt on the passnger side that is already shimmed to the max.
Whats it cost to spread the frame/crossmember anyway? Ive been asking about this.
