shifter alignment issue :(
I have changed the box and shifter in my C5, seemed ok for awhile,couldn t get it into reverse,no big deal, take it apart again and I see the output shaft on the box is not secured by the clamp,ok,tighten it a bit more and it is really tight now,work it back and forth a few times,and it starts spinning inside the brass clamp,everything is aligned properly,changed boxes again,same thing,what am I missing here ? If I tighten the bolt in the brass clamp anymore I am sure I will strip the threads. I can t see how the shaft can spin inside the clamp when the bolt is in the halfmoon slot, but it does. Any ideas would be appreciated,I have done the search and did everything according to the video,to no avail. 
Thanks Al

slipping shaft
The standard response to a slipping shaft is to either knurl it to expand it's diameter or to wrap the shaft in shim stock to increase it's diameter. The extreme action is to drill and pin the shaft to the block. Or just replace the worn part(s).

BRASS CLAMP????????????
Dont know if it brass or not.
Tighten it up. Use a MIRROR and examine the split on the one side of the clamp. If its smashed together,, YEP, it will NOT tighten any more. Use a 4" X 1/8" grinding disk on an air motor and open up the gap a little further so the bolt can bring it together more. OR Examine the bolt and make sure that the threads are long enough so they dont BOTTOM OUT in the lower portion of the clamp and not draw the clamp up enough to make the grip on both shafts the same. That can be corrected by using a washer under the head of the bolt or threading the bolt further up the so theres less shank under the head.
