So apparently the word from the dealer parts guy is the compact (shown above pt#) goes for $70
for the small one that takes donuts, the full size one is for a full size wheel. They can only get the compact before I leave so I may have to order it today and it'll be in the dealer from the local warehouse before I leave.
I guess a donut is fine for emergency, it'll all be interstate so no need for a full size...
thanks for the helpl, and for the record, I got the winch off and there's no cable hanging out of the hole, I wonder if that could be evidence of 'winch failure' in which case that outta be covered?
