Look at the Rovers North Website, work your way to Discovery I then onto the transfer case page. They have a correct detailed exploded drawing showing all part in their correct position with part numbers and prices. I would not even consider trying to find the stuff at any modern hardware store especially Home Depot or any such place.

I bought all new clevis pins and clips as mine was pretty bad. Look at the pics in my signature.

 

Is that all you care about...? Hey...Everyone...Look at my pictures...
Just kidding with you. That is a good set of pics. Now I know what exactly to look for and what to lube so my CDL will keep working. Thanks.
