[Chevelle-list] Upper control arms

[Ryan Langstraat]

I have two questions that seem kinda stupid but I want to make sure I do it right.....   1)   On the front upper control arms I had mentioned  that I replaced the cross shaft and that left me with a male thread on the outside of the bushing.  Once the center shaft  is mounted to the frame, the control arm slides back and forth on the shaft.  Do I just center it and tighten the nuts down against each other or is there something that I am missing?  Is there shims that I should have put on before pressing the cross shaft in?  I am open to criticism but I want to get it right while I am doing it.       2)     I have a set of 71 SS Rims.  I really dont like the looks of the blue bowtie that is supposed to be the center caps.  I was wondering if the center caps that say "SS" will mount to these rims with the retainers or am I outta luck?   Thanks for all the help Ryan   Been busy in the garage today dodging the tornadoes.
