What kind of key stock is it? Woodruffe keys are not square section. Perhaps I have got it wrong but on a taper it is normal to use a Woodruff key. A Woodruff is like a wee section of the moon, and it can rock a wee bit to follow the taper as you put the prop back on. This one isn't tapered, but it gives an idea....

Woodruff Metric key and Keyway Dimensions

This one is definitely for a tapered crankshaft....

In the future get a smaller car. 30 mpg is terrible. It should be twice that. End of sermon.
