I don't think F/A ski's were any different than the others. Here's the one I picked up on the 15 in MN. I also picked up my 3rd Intruder that day that will be just a rider. Have leads on 3 Drifters for a better belly pan so I can do a decent restoration before next winter. I have foam to do the seat correctly and a new windshield. Decal set is $55.
Very little will need to be done under the hood and is a running sled so that helps lol. Wish I could find out how many of these were actually built.
