Do you have one? Fry's should have one, I doubt Radio Shack does.
I got 'this' with the conversion kit. It came with 40 (not 44 IDE standard) pins!.
I found a cable company which should get me the right stuff.
BTW, Fry's referred me to the manufacturer; THEY referred me to Radio Shack, which did not have any idea what I was talking about!
