If it is a Kingswood Sandman ute and was L31 M41 air and steer it is the one to have! I'd pay $25k+ for that over here, + is condition dependant. Take $8-$10k off if it was a 173, 202 or 253 or $5k off if it was a manual. Looks like it may not have been air and steer though so it probably was a 6cyl or a 253 originally.
