Sorry not clear on what "this" is but I'll do my best. We'll get there after some back and forth.
First thing we need to establish is whether or not you still have the assist spring installed. I only reviewed this page and I don't see it mentioned. If it is still installed and your cruise switch allows it, there will be some slop before push-rod begins to move. Is this the case? Let's discuss.
Also regarding the clunk and notchiness, I'm concerned that the throwout bearing might be hanging up on the snout. I've felt this on @
Chen's car and made the connection after delving into
this thread.
edit: aaand I just realized you've posted to the same thread.
