Looking to reunite my husband with his '80 Kawasaki 440 Invader liquid cooled snowmobile which is sold in the mid 90s to a man who lived in the Milwaukee, WI area. The sled was special besides it being in great condition....my huadband had added (back in the 80s sometime if I remember right) onto the sled Arctic Cat independent suspension which was new on the market. Boy, did he turn the heads with this modified sled on and off the trails. If you've heard or seen of this sled, please let me know. Thanks.
