I got one. came from a 4/75 cruiser.
SOR indicates there was a cali model and a 49 state model, both from 1/75 to 5/75. check this.
they also want 75 bucks for a used one. I'll sell you the one i have, but are you sure it is your problem?
The computer, or black box, under the dash is notorious for having bad conections within it. mine had rust flakes in it (fordyce gets deep). I'd check this first, and probably reheat all the solder conections before suspecting the vsv.
