Diggler,
I had some concerns about the price of my UB40 flares for Cruiser 1. For my trail beater Cruiser 2, I didn't want to spend that much. I went searching for alternatives and found a company named Pacer that makes several EPDM rubber extrusions. I got the 2" surface mount extensions (that you can trim to fit to length) for about $40. You get 2 flares - I'm not sure how long, but there was plenty extra for my application. My sister works for the special parts department at Murray's Auto Parts here in the Detroit area. I would imagine that you could have your local parts store order them for you without a problem. There may be other manufacturers that make that kind of part, it wouldn't hurt to ask the guy (or gal) at the store.
I remember they also had some lip mount flares that you may be able to mount to the front fenders.
Even at $40 for a pair of extrusions seems pretty high (I work in the auto industry, and don't think that any of the EPDM parts were too expensive), but it's better than having to pay $100 for UB40's.
Hope it helps...
