Thanks, Ron!

EDIT: I can also take the wire forms to the local yard and try to find a donor, now that I have something that is close to the shape.

This one is a bit too bulbous for me. I was considering using a motorcycle fender blank, but figured it would end up like this. I think I read that one was done with a VW bug fender.

Nice but a tiny bit too flat. Gosh, I'm sounding like Goldilocks!
I considered dropping the back of the flare like that, but decided it would look too tail heavy. I'm only doing the rears.
I've decided that I'll redo the wire form so it's 29" across (same as the tire) rather than 31" (one inch extra per side) as it is now. 275/60R15s.
Scary, Discount has only one brand in that size now...Cooper
