my Hassy's hood had issues with the rear "flap" that lost it's position. For some reasons, the axle looks like it's too short (I suppose the hood's frame is a bit larger than initially).
So I tried to fix this by putting a new, linger, axle, but the spring that erects the read flap broke when I tried to put it back in place.
So, if you had a good source for this tiny spring, I'd be VERY happy.
