Rich- That classic chevy site seems to have a pretty good deal at $20. My google search hasn't turned up anything better. I'll probably just order a set and hope for the best! I'd rather swap them out and just save this set for something later to make it easy...as if anything is easy

Dave- I can only get half of your first pic to load, but I am curious what kind of clearance is acceptable so I will check back on that pic later.
