I used to have an old kayline top for my '73, it was the all snap version. It had a sweet feature where you could roll up the sides and back, but the roof section remained, for what I called "safari" mode. It had sewed in straps to contain the rolled up section. I can't find enough info on the newer fastrac model for the '73-75's. Can anyone tell me if the '73-'75 fastrac model has safari mode?
