The clip is about the size of a dime. The diameter through the center is about half an inch.
I guess I know most of answers that I need to know. I'm still tring to figure out if the engine is toast or not. I really like this car but an engine is gonna be hard to find here.
The clip I found looks like the lower left one. The only difference is mine is bent a little. Kinda like it got smashed and bent getting to the oil pan.
