If like me, you ever had to look for seat belts, you will understand that the following ebay auction is like gold.

 

If you have a 70-71, and even if you don't need them now, if the price is right; you should jump on it.

 

My story : I have been looking for a set of 74 for over 10 months now.  I can't find any under 400$ in a decent (working) condition.  In the meantime, I have settle for a set of universal aftermarket for 250$.
