Okay - I did not see the answer above so I counted the splines on a TRW box and the number is..........63. (not not 42)

I get the spline diameter as between .642" and .640"

I found this while researching an old Apex Speed Post.

It used to be models, slot cars, sports car, autocross, time trial, road racing.

my suggestion today is iRacing, indoor karting, time trial, racing or autocross.

Greg,

I don't think we are disagreeing. Once the camber is set, if it changes it has to be a issue with the spring/shock. So you have to check the bellcrank angle first to see if it has changed...

Yes, if you are doing a complete alignment. But say the spring sags or the pressure changes and you do a quick change to the camber, you might not remember in the heat of battle. I am not...
