You'd be better off to buy a used Bronco for $125 and use it as a test mule for swapping pickups.
I'm a Kay fan, but there is nothing above average about any part of that bass, and the pickups are just so-so. The comments about the neck and the electronics, plus the $40 shipping, are enough to put me firmly in "No go" territory. Maybe if I lived close and could pick it up, and if it didn't go higher...I'd give it a try. But I'd want it at $66, not $88.
