I'd like to help!
I've been buying my electronic components at Fry's; they carry the "NTE" line of products. (You can find datasheets at
http://www.nteinc.com/.) In the flasher, there are just a few resistors/capacitor/diodes, a 555 (or equivalent) timing chip, and a high-power PNP transistor. It's a simple enough design that it shouldn't take much to adapt it to the parts you happen to find at, say, radio shack; just make sure the transistor can handle lots of current, and adjust R3/R4 so that it turns on and off cleanly.
Unfortunately(?), I'm a couple of hours away from a period of extended travel, where I doubt I'll have Internet access.
I'll try to check back in when I can, but it'll likely be a few weeks before I'll be able to.
All the best,
