Hee Hee.
Sorry, I laughed out loud when I read your last post.
My wife asked what I was doing that I was laughing. I explained to her "been there, done that...".
Seriously, the only major thing to ever go wrong on my car was the coupler! My original design eventually went bad. Set-screws and misalignment. User error.
I was just driving along and it quit working.
I then made a new, improved version of the coupler - WELDED together. Works great.
I also think it's hilarious that I instantly recognize Geo Metro clutch plates that have been significantly modified.
Here's my first coupler, right after I trashed it.
Here's the coupler I have been using for the last while now. Works great. One-piece design, solid, welded.
