Thanks for the pictures Tom. At this point Im going to put my errant wrist pin clip mystery to rest and chalk it up to the fumble fingered mechanic. I guess I got lucky and my car will be back on the road sooner than later. I going to go ahead and replace the chain ramps however since I have easy access at this point.

Thanks for all of your help guys.
